How about the a rule that you have to remove trash in proportion to the mass you introduce? If you want to send up satellites now you have to organize to have some pieces of trash already there to be removed. When you finally remove the satellites you introduced, that counts towards your balance. But only at that time. As long as they are up you can't send up more without cleaning up some other people's junk.
You are already launching a satellite into an orbit where it will try avoid existing space debris. So, anything added to the payload to de-orbit space debris would have to spend delta-v adjusting it's orbit to match that of the space junk. Then it would need enough fuel left over to de-orbit the target.
I think it would be better if a certain amount of the launch cost would go towards a fund meant to de-orbit space junk.
It seems to me that we're in agreement.

I also seem to recall Musk saying the lasers on Starlink satellites used for communication could also be used for cleaning space junk. I'm sure that caught the attention of many militaries around the world.
