I would definitely do that, I would think why not.
But I'm going to do it only if I get hungry. If not, is I buy something else or am I going to keep it.
Well if someone was generous enough to lose money by selling you pizza and you wasn't hungry you could sell them and make some profit.
I see where the op is going with this but 10k sat for pizza does not make sense, I mean 10,000 bitcoin added up to the price of a pizza and obviously 10k sat does not.
Now a more realistic question could be would you buy a pizza at current price with bitcoin probably around 0.04.
I would say yes to both options.
