You should be able to use any money you want.
So if I want to use old buttons to buy an Xbox, I should be able to do that? What if the seller doesn’t want to take my old buttons? I value my old buttons quite highly, thank you. I think they would be getting quite a deal—my dear old buttons for a silly old Xbox? Come on, what’s there to think about?
Are all the people who read this noobyork blog that mind-numbingly stupid? If the seller won’t take your buttons, you can’t successfully use them to buy the xbox (but you’re free to try and they’re free to accept) and buttons likely will never become a private currency. Other things have and will, without being proactively imposed top-down on the masses by the State as monopoly issuer of legal tender. See Hayek’s book on the subject (Denationalisation of Money) or the more recent work of monetary economists like Lawrence White and George Selgin to understand the economic history and theory.
