> A deed does not refer to a specific thing. It only does so in daily life as a matter of convention. It is the authority of the banks or the government or whatever that gives your particular deed any weight at all. A deed, like a dollar bill, is a piece of paper with no value. Indeed, a photocopied dollar bill has no value whatsoever. It is only our collective agreement to pair value with officially recognized papers that grants those papers value.

What? A deed, per common law, is a legal instrument which affirms ownership of something. I'm not going to talk about value as that is independent of the purpose of a deed (you could have a deed to something that everyone agrees is worthless, but regardless you are the owner according to the government(s) in question)

Again, if you have a central authority an NFT is unnecessary and pointless to begin with. Nothing you've said really refutes that. All of the functionality of an NFT can be trivially replicated by a central authority, and indeed it already is.

> Anyone can sell anything

No, they can't. By your own logic, anyone can do anything. Surely you already see that is not true. We live in reality, and in reality others must recognize actions in order for them to be recognized as legitimate.
