It's not about seeing everything, it's about seeing what's good, and how that's scattered across a dozen or more services where it's buried under mostly mediocre/bad content.
Sure, sometimes there's an option to just rent/buy digitally, but often that ends up being way more expensive than just buying a physical blu-ray version.
Case in point: If I wanted to stream Battlestar Galactica (2004) in Germany then the first option for that would be Amazon Prime Video. Even tho I pay for a prime membership, buying all 4 seasons digitally in HD quality, would cost me 92€, there is no option to just rent them.
While ordering the blu-ray set for the whole show, on Amazon with delivery tomorrow, would cost me 48€, nearly half as much and I get a physical version I can use as often and wherever I want, even if the unthinkable happens and Amazon goes out of business.
Why does the clearly inferior version of a product cost that much more?
I honestly don't see why anyone needs more than maybe two streaming services. Do you really need to see everything? Even during the pandemic, two seems to be plenty for most families.
Imagine arguing that movies are too expensive now because you have to see a movie every day. The obvious solution is to prioritize what you view and watch fewer movies.
For most people the current approach is better: spending $20 or $30 a month instead of $80 -- and with much better choices available, and often without any ads.
