Crypto has shown some rules are unnecessary or even harmful. They should be repealed, across the board. In other cases, many cases, it's reinforced some rules' necessity. Their scope should be broadened. That's what's going on here.

This, alone, is insufficient. AML duties aren't discharged by an "I promise I'm not a money launderer or tax evader" checkbox.
