It is quickly turning into one of these things that there are laws for, and everyone thinks it is rediculous, it is never enforced and DE facto not a law.
And what a shame that is.
I was with you until this. Copyright is a legal fiction, if it's no longer working the world will adapt. No need for shame to be involved.
Some fictions are readily dispensible. Most are not.
What they are not however is laws of nature, divine right or revelation, or immutable.
Limit on the law-of-nature bit: law is often a highly probable outcome of various power dynamics, political, economic, social, cultural, etc.
