Intermediary platforms are like this, yes. They take place of what should be infrastructure.
I hope everybody understands that if some standard, easy to get into payment and catalogue system were in place, nobody would need these platforms. If you could pay to an IP address as easily as you can ping it. I mean, I think identities should be cryptographic in that, but you get the idea. It should be lower level functionality.
I’m not sure how IPFS is different from torrents. I don’t think it’s solvable with blockchain too.
It’s nice that someone’s made electronic distributed gold, but that doesn’t include a payment system.
EDIT: in any case, I’m aware of various systems covering small pieces of what I’ve described.
