> Not everyone wants to engage in all of the PR/marketing stuff that's necessary to make any money from that

That's not a difference, PR/Marketing is already used to profit over IP work.

> Even if that were sustainable why do you think that content creators should be fully content living of UBI + a few pennies in donations while people working in most other industries should be able to money the same way they previously did?

This is assuming creators are fully content on how stuff work now, and I'm betting that's not the case for the vast majority, most of them cannot make end meets with the current system, regardless of how hard they work on their book/song/game/etc, and they have to have a side job just to put food on the table.

> IP protection (even if often implemented in a suboptimal way which of course should be improved) have been one of the primaries force behind human progress over that last 300+ years.

That's a bold claim. Most of, if not all, human progress on this period is directly attributable to the use of fossil fuel, from the steam engine to the modern use of it, and how it empowered us to do so much more with less human-hour.
