It's fine that you realize that copying is inevitable and unstoppable, but you are still talking as if copying is immoral. It is copyright that is immoral. Copying is a natural right, and the way that the universe works. A radio broadcast or a concert or even just singing in the shower creates countless echoes of information. A shining light on a painting or written page bounces photons into the eyes of anyone looking that direction. Copyright is an entirely artificial restriction on these wholly natural processes. And for what purpose? To encourage the creation of more art. That is hardly the only way to encourage artistic endeavor. As to complaints that artists will starve without copyright, no, they won't. To support art, there is patronage, crowdfunding, performance, and endorsements, to name several other ways.
For copyright to really work, we are supposed to ignore all these echoes. See the movie at the theater, then buy it on DVD (or pirate it of course) if you want to see it again and your memory of it isn't satisfactory. The day may come when we all have inexpensive devices that augment our memory, allowing us to perfectly recall anything we see or hear and copy any of that we wish to another person or data repository, and then what of copyright? Copying has become so much easier to do over the past 40 years that copyright is already absurd now. With technology like that, copyright will be ridiculously archaic and worse than useless, it will be a major hindrance to the ability of its followers, if any, to function in society. For now, copyright blocks and slows the coming of the digital public library, a huge, huge improvement over the traditional library full of bound papers. The private bookstore is dying, and good riddance. Accepting copyright is like accepting a proposition that we should all use only one arm until the holders of the rights to use our other arms grant us permission, and each time we want to use our other arm, we have to ask for said permission and pay a fee. The industry has done an effective job of pushing the propaganda that copying is stealing, and hurts artists and is therefore unfair and immoral. They've confused the public with the seductive simplification that property is property and there is no difference between the physical and the intellectual variety. It's a simple, easy way to view the matter, but it is wrong, and the secret is out now. More and more people are seeing through their propaganda, ironically helped by the industry's clumsy, extreme, and harsh enforcement tactics that earned them the moniker "MAFIAA". For yet more reason why the industry is parasitic, a broad and extensive propaganda campaign, plus a terror campaign to scare the people who weren't fooled or who don't care, is just the sort of thing one could expect from parasites.
It's not just the future in which copyright doesn't work. It never has worked well, ever. Civilization would not have advanced to where it is today had ancient civilizations been able to lock down all information. No matter how much an ancient civilization wished to keep a new battle tactic or weapon secret, once used, their enemies would see it, and the survivors would not find it hard to understand and duplicate, or perhaps counter, or even improve.
