How is this not just outright snobbery about what people should enjoy?
I like high-scale, ambitious entertainment.
It may or may not be true that “high-scale, ambitious entertainment” is unsupportable without copyright. If it turns out to be not supportable, it would be like the pyramids: Large, impressive, and expensive things which the structure of our society and our economy can no longer support the constructions of. I.e. the society we live in could concievably be re-organized to again support the construction of pyramids, but we choose not to do that, in order to have a modern society and economy instead.
For some people. Believe me, there are lots and lots of people who do not share that experience.
That's what the public domain is for, of course. It's too bad that this limits us to 1923-or-before material (in the U.S., and ignoring non-copyright-renewed stuff from later in the 20th c.) but that still covers centuries of shared culture - even millennia, in some cases!
Absent an organizing effort, it’s unlikely you’ll catch someone who has read, say, Dracula for the first time recently just like you have and can share that initial enthusiasm for the material.
You are supporting an army of workers to make a decently budgeted film, for multiple years.
If we reach 100k we'll make sure Han Solo shoots first.
It doesn't make sense. People should be paid for providing a service, whether it's a hamburger or a movie. You don't pay someone before the goods are delivered. The modern system of pre-funding and patronization is absurd for many projects.
Strictly speaking, you don't have to do this. You could make the product, send it under a strict NDA to a variety of widely-trusted 3rd-party reviewers/critics, with whatever sort of protection against leaks you might require, then put the existing product for crowdfunded "ransom" (Like Blender was, after the original company went out of business), building in whatever return you might wish to ask for in exchange for bearing the ensuing risk. This doesn't require ordinary copyright protection at all, only a very limited-in-scope protection for private, unpublished stuff.
(The "ransom" model is in fact already potentially-applicable to a lot of existing content that's generally considered worthless, but that, much like Blender itself, might be valued more in the context of an open release. Transaction costs - namely, wrt. the exceedingly-common case of "orphan works", with unknown rights-holders - get in the way of it, however.)
You produce whatever small part of your work you can afford to on couch change, pizza favors and family support and sell it. Fund the next part from the proceeds of the first.
It lives on today in webisodes and patreonage, or, hell, TV shows, but some of what we now consider great literature was produced as serialized chapters in magazines, and only after the fact bundled together as a single volume novel.
Maybe box-office blockbusters funded as multi-million dollar investments and released all at once were just a temporary aberration, like the "album".
This is how it should be - there is simply no rational case for mindless entertainment ("TV/Movies/Music") that costs on the order of $10M or $100M to make!
