Not at all what I said. You can spend them any time. But if you spend them, you have to realize that you lose the current value they have, not the value you got them for. So that Pizza costs you 5$ more with bitcoin.
In a certain sense, yes, sure. What I'm saying is that, due to appreciation of my Bitcoins, those $5, as well as the actual price of the pizza, were essentially a gift to me from the Bitcoin community.
I don't mind spending free food tokens that were gifted to me. Even if spending the free food tokens costs me fees (expressed in free food tokens), and I might possibly trade those free food tokens for a slightly higher amount in dollars (but incurring other fees). Especially since, if everyone stopped using their free food tokens, everyone's free food tokens would stop being usable.
I would certainly maximize my pizza buying power by minimizing the transaction fee costs. I.e. convert a larger fraction to USD and incur the overhead only once. If you convert the value of 4 pizzas, you get a 5th for "free". But maybe I just like pizza more ;)
