I dropped cable, which had everything 'in one place', because it forced me to take everything and pay for it. What you see as a search and access problem I see as a new choice I never had before.

I use a Roku, it has a search feature that searches across a bunch of streaming services, I can see where is show is available, how much it might cost, or if a subscription is required. I'd argue that you have a search problem.

The entertainment industry wants you to buy it all and pay an ever increasing price for it, while including as much advertising as possible. The all-in-one service you are looking for looks a lot like cable, where you get a giant bill and no choice to remove things you don't want to pay for.

Given the way copyright works in the US, there is no 50 years in the future where things are freely available - future generations can still cash in on things copyrighted today.
