Except each single one of the tiny ones won't necessarily explode every operating orbiter it touches. Again the total mass is smaller.
And I think a uniform cloud of small bits would be easier to clean up as well. Imagine catching a couple rabbits vs sweeping up a bunch of ants with a broom.
Actually I would say a uniform cloud of small bits is way more predictable as well. There'd be some set amount of abrasion that a spacecraft could reasonably experience on its way to orbit and in orbit that scientists could engineer for, rather than just hoping a big 'un doesn't strike it at random and blow it up.

I didn't mean gently coalescing, I specifically meant smashing into each other in an inelastic collision to shed significant amounts of orbital energy and deorbit. There'd be bits flying off but overall there's now significantly less space junk in orbit and those bits might be picked up by future magnetic junk satellites floating by.
Also with the magnetic arm, I outlined above why a magnetic arm might be better than a gripping arm. Maybe the magnetic satellites could just be giant wide rotating + signs in orbit (with the arms extending vertically). They could tessellate the sky at multiple orbit levels and could slowly use fuel to gradually shift their orbits to get even more coverage.If magnetism's inverse cube law is a concern we could also just try heavily charging the junk-collector satellite's arms once it's in orbit.
Also the point is it won't necessarily need to be in contact and it won't be combating gravity. In fact if the junk-collector is in a lower orbit it'd be in tune with gravity. If it gets it to drift down even some small amount that's progress; also since I imagine the junk collector would be in front of and behind the junk for roughly equal amounts of time, then the tangential momentum change would probably be rather small, even despite orbital speed difference between the two bodies.
I understand a big problem is just the large distances between objects, and that this method is more useful for high density Kesslery situations like you mentioned, but I'm expecting there to be more and more satellites launched in coming years and hopefully statistically over time these rare occurrences could add up to some meaningful cleanup.

Hold on, S, I think you’ve contradicted yourself there. You said a tiny magnet is able to pull an object against gravity, but you also said that magnets in space wouldn’t do that. I guess the big difference is distance there. But what if the magnets were really close, orbiting a few meters below? And the satellite you’re trying to deorbit is highly magnetic as well? Also you should consider magnetic potential energy in this situation as well. The idea is that the magnetic satellite would orbit closer to the earth than the main satellite, and would pull it radially inwards. Yes, the main satellite would accelerate and gain momentum, but it would be designed so that it’s mostly radial acceleration and not tangential acceleration. Once the satellite is in that closer orbit where orbiting bodies have higher tangential speeds it finds it has a relatively small tangential speed to sustain that orbit, having nearly the same tangential speed as in its original farther orbit, so it deorbits from there.
What if the magnetic satellites had long vertically extending arms that could bring magnets closer to any orbiting satellites they want to deorbit? It’s essentially grabbing them out of orbit but without clunky grips you might do it mechanically with, and additionally could deorbit multiple objects, including tiny objects, at the same time. Plus if you put activatable magnets on satellites, they could tend to coalesce together once they use their fuel and shed their orbital momentum on their own.

Yeah old bells that ring a bell a bunch of times tend to have electromechanical components. The signal from the doorbell starts a cycle where an electromagnet switches on and off which cycles a solenoid hitting the bell a bunch of times.

What if you have a bunch of magnetic junk-collecting satellites orbiting outside of normal operating radius near where dead satellites would maneuver and be sucked radially into a closer-to-atmosphere orbit where they would deorbit. Theoretically they'd be traveling at a slower tangential speed than the junk-collectors so they would deorbit and the junk-collectors wouldn't. There wouldn't necessarily be physical contact between them.
In fact you could have two magnets in the satellite with opposite orientations. Then you can rotate one of them and boom, you have a magnetic satellite that can be better attracted to any junk-collector magnetic satellite. In fact they would naturally want to align so maybe you just release some latch holding them in opposite orientations. The point being you use less resources per satellite launch than using rocket fuel to deorbit. Is that the problem with deorbiting by thrusters, the extra launch cost?
I guess a problem could be the sheer size these magnets would be. Plus maybe interference with operating satellites' sensors.
Now it kinda just seems like a dumb idea, but I'm just theorycrafting here.

Swapping a satellite for a glob of metal salts, hydrogen gas, and feck knows what other resulting compounds seems somehow worse.
I think MrRoboto75 was arguing for instead of an acid dispenser, the use of a fuel tank that could deorbit the satellite.

There's now 3.2M members of r/wallstreetbets in total at this point. I think the average investment amount of the members is at least $1000. Quite possibly more. That's already 3.2B dollars. They're like a huge retail investors' hedge fund now. It's like they accidentally unionized into a working class investors' union and are just now discovering their power.
But do you think this may be a good thing?

I literally posted a week ago or something about the greatness of the unique flavor that is r/wallstreetbets. It is very amusing.
They also have a pretty big influence on the market, to the point where an alleged CCP infiltrator was discovered on the sub. I think across all their members they're equivalent to like a billion-dollar investment conglomerate, especially given their tendency to align themselves with each other.
Which makes me wonder, is r/wallstreetbets an important tool of us working folk? The one billionaire which is on our side in the class divide?
The subreddit r/wallstreetbets has an interesting type of humor. It’s so innovative it’s kind of hard to describe. Like doing something ironically and unironically at the same time. Like doing something idiotic while being fully aware of the idiocy. Like the way 4chan calls itself autism but at the same time also putting real money into it in a grand act of yolo.
