Which was why I was trying to make my point ... which I'm having a hard time describing.

I don't think we ever go from using a fiat metric (e.g., USD) as the unit of account to going to using BTC as the unit of account.

I think the price for a good or service will involve a calculation using the underlying data sources in real-time (or close to it). These data sources could include commodity prices, labor costs, property costs, and capital (interest rate) costs, etc. Then once that calculation provides a result, then that is what then gets spit out as the "price" ... in BTC, or in USD, or in EUR -- in whatever medium of exchange the buyer wants prices presented in.
