how to people put it back in bank

question - i was just informed that I cannot transfer crypto back to my bank account, AML? Is this true? How are people who are taking payments this way transfer it to bank?

EDIT: I think everyone is missing my question or Im still confused and dont realize these methods avoid aml. SO let me mention - I am aware how to get it into the bank. My question is : How are people avoiding frozen funds, AML, etc that comes AFTER that.
