If you're saying "you should not restrict ALL culture to rich people" then, we're not. There is plenty of culture available for free on YouTube, or on broadcast TV channels, or FreeVee. And paying for one paid subscription doesn't make you rich, $10/mo or whatever is an accessible price for a subset of digital media to a non-rich person. And those libraries are sufficiently large that you would not run out of material to watch even if you only had one service.

If you're saying "everyone should be provided literally all digital content for free at all times" that is a pretty extreme position which does sort of break the economics of any content being produced. Digital content would have to be plastered in way more ads or be government subsidized or something to have the money to make more of it. That's not a political position I'd be on board with.

If you just want the current system but with you being allowed to download the stuff you want to see on services you don't pay for...again, there's an argument for that, but let's not pretend it's some high minded one. It's selfish. You probably have the money to pay for HBO Max for one month to watch the new Game of Thrones and the Barbie movie but you don't want to pay money and it's really easy not to.
