i think you gotta realize that at least a lot of people dont really pirate to save money. they pirate because they cant be arsed to deal with the shitty other platform that are plain inferior and take way too much effort to figure out.
wrt books/ebooks: i actually do occasionally buy them on amazon, drm be darned. but i dont actually try to create an archive either. thats the big difference - if you actually wanna keep what you read/watch available forever... you just gotta pirate it. there is no other way. a lot of people enjoy building an archive. they're all forced to pirate almost everything.
Not just enjoy, many times you'd have to if you want to keep your citations and annotations. Otherwise it's the same type of fiascos over and over again

However, for TV and movies, I find the pay site experience to be too poor (last I checked you couldn’t even stream from Amazon video if you run Linux). So I pirate everything.
I think Bandcamp is the perfect site for purchasing music. They’re transparent about what they pay artists and labels, and a purchase nets you unlimited streaming plus DRM-free downloads. This is the model the sellers of these other mediums should be following. I buy a lot of music, all because bandcamp is so great.
