Why not spend the BTC and then buy it back? That is your zero-sum game. You can even take advantages of sales that are offered to bitcoin-only purchases.
Bitcoin needs to become more "everyday" before it will be generally accepted by the masses. Using it will lead to that, and will in turn get more merchants to accept it and realize the potential. As this trickles down to suppliers, one day we will reach a point where the whole cycle from supply to manufacturing to shipping to store shelf can be transacted in bitcoin, and THAT is the time when it's value will really skyrocket.
So keep your satoshis. Keep your balance the same (or increase it). But support the notion and spend and rebuy the coin.
