Is there any justification for the leverage penalty? I understand that it would apply if there were a finite number of agents, but if there's an infinite number of agents, couldn't all agents have an effect on an arbitrarily larger number of other agents? Shouldn't the prior probability instead be P(event A | n agents will be effected) = (1 / n) + P(there being infinite entities)? If this is the case, then it seems the leverage penalty won't stop one from being mugged.

If our math has to handle infinities we have bigger problems. Unless we use measures, and then we have the same issue and seemingly forced solution as before. If we don't use measures, things fail to add up the moment you imagine "infinity".

Then this solution just assumes the possibility of infinite people is 0. If this solution is based on premises that are probably false, then how is it a solution at all? I understand that infinity makes even bigger problems, so we should instead just call your solution a pseudo-solution-that's-probably-false-but-is--still-the-best-one-we-have, and dedicate more efforts to finding a real solution.
