I assume you are being sarcastic. But what you are suggesting is exactly what we need. Why did it be a problem for people to move money around willy nilly? Why do we need controls?
We do it mainly to help find criminals, but there are other ways to do that.
We also do it to help find criminals.
And if the only reason we do it is to stop people from legally moving money around, then we need to stop it. Will criminals and terrorists benefit? Sure, but they can also benefit from other legal things as well, like cell phones and the Internet
Ok. And is the a reason to cripple our entire financial system? People can avoid paying taxes already.
Most legal forms of income are already tracked, outside of kyc.
