You can imagine a world in which we have laws allowing broad recipes to be patented. For example, some restaurant chain might register the patent for spaghetti, and you could only ever eat spaghetti at their chain. 100 years from now, we'd likely have some MegaBlockbusterRestaurant chains that spend ridiculous amounts of money on developing new and unique recipes they can monopolize. And someone from that era might say, "What if we stopped allowing this?" And someone could reply, "But tens of millions of dollars are spent on this. It's big business!"
And they would be right ofc. It's a factually true statement. But… so what? I don't mind living in a world where everyone can remix everyone else's recipes, even if it means we don't end up with MegaBlockbusterRestaurant chains.
Perhaps a world with no/weaker copyright laws might be one where money flows toward live performances over recorded experiences. Not necessarily worse imo.
Or even towards patronage. Crowdfunding is already a thing. Government grants are already a thing.
A lot of content, and software, takes a huge capital investment to create. Blockbuster movies can cost hundreds of millions of dollars to produce, AAA games can certainly cost tens of millions. This is also why open source and and Libre software never took over the world the way many of its proponents assumed it would back in the 90s. Many applications take more than just coding chops to create, it takes QA engineers, artists, designers, project managers, market research and domain experts dependent on the market segment (medical experts, radio engineers, etc). It can take a huge capital investment to put all that together and that money needs to be made back somehow.
Even music takes recording studios, sound engineers, session and backing musicians, artists for the album covers and posters, music video production teams, etc, etc. It’s a serious business. A committed artist in their bedroom can work wonders, but not all music and associated material can be produced in a bedroom.
