However if one already owns bitcoins, this problem that you have becomes non-existent.
You missed OP's point though, he/she was talking about bitcoin being part of everyday transactions (ie. buying a cup of coffee). Although we probably won't see bitcoin be adopted as a mainstream currency (used by almost everyone) in the near future I think it is possible with all the progress and development going on with cryptocurrencies. Just don't expect to see it anytime soon.
