Care to run down that rabbit hole? I happen to think copyright is a concept which is intrinsically broken with the advent of modern computing power and connectivity.
While I happen to agree with you, I think it's important to distinguish the two:
What A.G. Barr is insinuating is to regulate algorithms.
Copyright is regulation of implementations.
For example, GPG is a software implementation of encryption algorithms. It has a copyright (used as the basis for its copyleft license). RSA, however, is an algorithm: a mathematical reality that can be described by copyrighted works, but never itself copyrighted.
A.G. Barr has expressed a desire to compel every American who implements that algorithm to do so incorrectly.
