Amen. I pay for at least a dozen services and still have dozens of shows and movies from the past decade that I can't get. >10x going further back. Many are only available on the grey secondhand market. For example: Combat!
I'll start considering rights holders arguments when they're not capriciously gating or scalping on content, and are not limiting their content to their service du jour. The music industry has solved about 60-80% of this problem depending on what you like. The movie and series side has regressed to become worse and more expensive than blockbuster was. Shame!
Paying for Amazon Prime, Netflix, Hulu, Disney+, and HBO Max and still not coming close to "almost every" movie isn't cheap.
And, yes, we want it from a single origin. It's not our fault that the movie/tv industry is a dumpster fire.
