People, if they were entertained at all, were mostly self-entertained back then - they played instruments and such. There was hardly if any passive content consumption back then. Before 1710 there were no novels (novels as literary form weren't invented yet), obviously no movies, video games or music recordings. There was practically nothing to protect, apart from musical scores or theatre plays.
I find it amusing that you reduced the works of Greek and Roman philosophers and poets, the entire Renaissance, the whole Library of Alexandria and indeed, the Bible, to "practically nothing."
I fail to see how, say, the Nth installment of Marvel movies is somewhat more worthy than all of that.
Movies which, I might add, are already hugely profitable, even though they're massively pirated.
The sheer amount of work and content you are dismissing as "nothing apart from musical scores or theatre plays" is mind boggling.
Here are just a few examples off the top of my head, to whet your appetite:
- The OG superhero story: https://en.wikipedia.org/wiki/Epic_of_Gilgamesh
- A fairly popular adventure story you might have heard about: https://en.wikipedia.org/wiki/Odyssey
- This one even has "comedy" in its name, if you needed convincing: https://en.wikipedia.org/wiki/Divine_Comedy
