You won't destroy the progress completely but there definitely will be a lot of unfairness like people monetizing someone else's music due to having better SEO skills and more free time than the artist. And the artist cannot hire SEO specialist because he has no money (let's assume he is an electronic musician and doesn't gather stadiums).
And the results are observable empirically: very few people are told by anyone that's been out in the world that they should choose to become a writer or an inventor, because writers and inventors simply don't make that much money. The system you claim is so necessary seems to be completely failing in its core mission.
For example, take a look at writers making a decent living on a platform like Substack. Copyright is literally doing nothing for them. People can freely copy their substack and post it everywhere online. The value is that the platform provides a centralized location for people to follow the person's writing, and to build a community around it. In cases where artists and inventors have become rich, I look at the mechanism behind it, and often it's an accident that had nothing to do with intellectual property rights at all.
While I don't disagree with what you are trying to say, saying it this way is hyperbolic. There are so many people doing important things. Think about parents.
Or simply for the most minimal of external rewards: recognition and respect.
Or for the purest: seeing others live longer and happier as a result.
Look at open source. If Linux had been closed-source with licensing fees, the internet wouldn’t exist as we know it. Open ecosystems build faster. Contributors innovate because they can build on each other’s work freely.
Market pressure drives innovation. Reputation beats monopoly. Monopolies slow everything down. And collaboration multiplies progress.
It's not at all unusual for popular/iconic furniture designs to be copyrighted.
Reality is people who invent truly original, useful, desirable things are the most important human beings on the planet.
Nothing that makes civilisation what it is has happened without original inventiveness and creativity. It's the single most important resource there is.
These people should be encouraged and rewarded, whether it's in academia, industry, as freelance inventors/creators, or in some other way.
It's debatable if the current copyright system is the best way to do that, because often it isn't, for all kinds of reasons.
But the principle remains. Destroy rewards for original invention and creativity and you destroy all progress.
