I'd love to see some kind of cross-publication subscription service where I pay 20 bucks a month, and I can read, say, 100 articles from the 40 largest publications.
And in fairness this does exist on Nostr (I think in multiple forms). It's just not widely used. Not least because most on Nostr don't really believe in the idea that information can be owned in the first place.
