> I disagree that you can’t own something that isn’t physically controlled by you.
We're not talking about "something" in general, but about digital infrastructure.
> Almost all of us have money which is not kept on our persons or property, in banks and investments. I think people would be outraged if someone told them it belonged to the bank.
A better analogy is if you have a cryptocurrency wallet managed by Coinbase. You don't own. And they can in fact suspend your account (and probably take your crypto) if they don't like you.
I’m not sure that analogy contradicts ownership. Physical assists can be seized or stolen also (if Deloitte’s AI doesn’t like you) but it doesn’t negate the concept of ownership of those
Maybe possession would be a more accurate legal term? You can own something that isn’t in your possession (eg might have been loaned, stolen, etc) or possess something that you don’t own (eg the other side of the transaction)
