Then fix that instead of blowing it up. Because IP law is also literally the only thing that protects the little guy's work in many cases.
Arguments like yours are kinda unfathomably incomplete to me, almost like they're the remnants of some propaganda campaign. It's constructed to appeal to the defense of the little guy, but the actual effect would be to disempower him and further empower the wealthy major corporations with "big enough warchest[s]."
I mean, one thing I think the RIAA would love is to stop paying royalties to every artist ever. And the only thing they'd be worried about is an even bigger fish (like Amazon, Apple, or Spotify) no longer paying royalties to them. But as you said, they have a big enough war chest that they probably could force a deal somehow. All the artists without a war chest? Left out in the cold.
It definitely does some of both, and we have no obvious measure or counterfactual to know otherwise.
You also have to take into account not just if optimal reform or optimal dismantle is better, but the realistic likelihood of each, and the risk of the bad outcomes from each.
Protect even more conceptual product ideas seems pretty strongly like it will result in more of a tool for big guys only, it's patents on crack and patents are already nearly exclusively "big guy crushes small guy" tool, versus copyright is at least debatably mixed.
It's super obvious, unless your perspective basically stems from someone who was mad they couldn't BitTorrent a ton of movies.
I mean, FFS, copyright is the literal foundation for open source licenses like the GPL.
My sense is a lot of the radically anti-IP fervor ultimately stems from people who were outraged they could be sued for seeding an MP3 (though it's accreted other complaints to justify that initial impulse, and it's likely some where indoctrinated from secondary argumentation somewhat obscured from the core impulse).
That's not to say that there are not actors who abuse IP or there aren't meaningful reforms that could be done, but the "burn it all down" impulse is not thought through.
Yes it is a genius move that copy left used copyright to achieve their goal. But the name is literally reflecting the judo going on in that case. Copyleft licenses also does have a lot benefits to big companies as well too so it's not strictly a David vs Goliath victory.
I don't think it's a commonly held belief that copyright benefits small YouTube creators more than it hurts them as a concrete example, they seem to live in constant fear of being destroyed in an asymmetrical system where copyright can take away they livelihood at any moment while not doing anything to meaningfully protect it.
