You have a lot of claims there, do you have sources?

AML regulations do plenty, and they start with banks checking for sketchy transactions and not executing them. You can also look up several cases of very large penalties for breaking these laws. The US crushed a couple of Swiss banks a few years back, the longest operating bank which had been going for hundreds of years was effectively shut down by money laundering judgements.

It seems you want to have small financial businesses not be responsible for people using their services to commit crimes... well too bad, I say. You don't get a free pass to aid and abet crime because you're small. Like many things, the business of facilitating financial transactions isn't just keeping a ledger and presenting a nice interface to it... the real meat of the business is accurately keeping transactions on par with regulation and resolving disputes. The obvious part of the business is the easy part, the hard part is what you get paid for.
