As I said, that's precisely because the world works the way it does, rather than the way you wish it did. The bottleneck for lots of otherwise extremely profitable criminal endeavors is their reliance on traditional financial intermediaries.
> That touches on one form of corruption.
I'm talking about the type of corruption that keeps entire countries from developing economically. I don't know what you're on about. And no, your series of suggestions, which amount to saying make the current regulations stronger, doesn't come close to closing a huge loophole created by giving blanket immunity to financial intermediaries.
Edit: honestly it sounds like you ran into some unfortunate situation somewhere and hold a personal grudge. But that's not a particularly meaningful basis for policy recommendation, especially given that it's quite clear that you don't understand the domain particularly well.
> Most corruption involves things like (not directly financial) preferential treatment. If I give you a raise you don't deserve, give your child preferential treatment at my school, or cut a sweet deal for your company, that doesn't show up in a Paypal transaction.
Most corruption is like this when you live in a country where corruption isn't much of a problem.
