I agree with you on most points but the idea would be an Airbnb or Uber that don't take a large fee and make a large profit right? I know this is all wishful thinking stuff but it doesn't seem fair to say this is terrible because companies that exist to centralise transactions within a space won't want it. You're right that it doesn't seem to work without money though, and if it is a centralised service it's way more expensive than before. It all feels too theoretical when you get talking about multiple blockchains.
