Someone should copyright the American flag and popular advertised variants of blue/white/red and something alike and start DMCA'ing politicians, maybe that would wake them up to how bad the law is?
That's not how you get copyright, the creator of a work automatically gets the copyright. You can sue someone for violating your copyright, but if you tried to claim copyright of the US flag your case would get thrown out immediately.
You have to register copyright to claim statutory damages. You can claim actual damages (lost sales) but statutory damages are where the money is at.
