The reason people pay is the convenience! The DRM isn't required for that. If they dropped all DRM tomorrow, they would lose far fewer subscriber dollars than they spend on DRM implementations, license servers, key management, etc. They're just greedy, want control, and want to keep it illegal to break out of that control.
Meanwhile, any media "purchases" you make are gone in a blink if the company you bought them from goes out of business or just decides they don't feel like offering the service anymore. The funny thing is that most of the buy-to-"own" (where you don't actually own it) prices are similar to the cost of a DVD or blu-ray disc. Ditto for Kindle books and their paperback counterparts. All the promises of digital distribution giving consumers lower prices were predictable lies.
Regarding purchases and licensing, those are still stuck in the same business model and pricing as in the analogue days, this is true. But saying overall consumer prices are the same is ridiculous, since all-you-can-eat content subscriptions is a massive transition with no comparable offerings in the analogue past.
If you want to culturally enrich people, there has never been a better time to consume huge amounts of quality stuff for barely any money.
