Thank you. This definition confirms what I was getting at by calling it "semantics"
It doesn't matter to me what the UOA is. It can be USD or gold or seashells. If my purchasing power continues to rise by holding what I value, that is all that matters to me.
Is there an argument for why it is important to have the actual UOA be Bitcoin (or USD whatever)? Isn't this just a sort of collective agreement to simplify international commerce?
