Agreed. I'd like to purchase a cheese sandwich at my local BTC-accepting food truck, but I'm going to skip it this week precisely because I might be able to buy twice as many (or half as many) sandwiches next week. Things are so volatile this week, that even nearly-instantaneous transactions USD-->BTC-->BTC-->USD (whose utility isn't affected by the price of 1 BTC) aren't guaranteed to happen as expected. Better to wait a week for things to chill out. They will.
