Your answer to the first question is hiding in the second sentence: if the price is anchored in dollars, the sats number floats and you never have to re-tag a shelf. It does mean you are running a dollar business with a bitcoin treasury, not a bitcoin business - when the price rises your shoes get cheaper in sats instead of more profitable in fiat, and when it falls you eat that difference quietly. Fine, as long as you know which one you signed up for. The part I would still push on: the sats do leave, just not at checkout. The factory invoice and the tax bill are both denominated in fiat, and a shop holding nothing but sats pays those by selling sats. Economically that is the same conversion you refused at the till, only later, with the exchange risk moved off the customer and onto you. That is not a contradiction, it is a duration bet, and you are taking it on purpose - which is more than most shops that say "bitcoin only" actually do. The honest version of your position is not "we never convert", it is "we hold for as long as our fiat obligations let us". That is a treasury policy, and a defensible one, and keeping costs low is exactly what makes it survivable.
