The interstate commerce clause is about commerce between states, it's not about imposing legal restrictions on future classes of Congress. There is a reason why the Constitution requires 2/3 supermajorities from both chambers and 3/4 of state legislatures. Any legal restrictions targeting members of Congress (that aren't broadly applicable to everyone in the U.S.) have to go through the constitution.
