Don't you think that it can be used as a basis to establish ownership of all those assets that are online though? Eg, I could see the basis for an automated billing for NFT + smart contracts for assets I have used online.

I'm not sure where you are with property ownership - perhaps this is a reference to Proudhon, or perhaps a reference to the legal fiction that we use to navigate this system? Whatever the case, given time, the legal system would likely end up supporting NFT ownership + usage fees I think.
