Indeed, as I've said in the past, money is a technology, and different technologies can be applied to different purposes. The "major" world currencies are designed to be used as a temporary store of value, medium of exchange, and instrument of economic policy. Bitcoin could be applied towards different purposes.

Stocks would continue to be denominated in shares. I've never heard of a stock being denominated in currency, but maybe there is one out there like that. A share is usually something like I own 1/N of the interest in the company so the formula of ownership is m/N where m is number shares you own and N is the number of total shares (some simplification here, but roughly accurate). Market clearing determines how much people will pay for a stock, which happens in all sorts of currencies.
