Half-measures == Half-reached goals.
When you want to buy something in a grocery store that does not accept bitcoin and does not even know what it is, what do your "full measures" consist of, exactly?? Forcing the marchand to accept your bitcoins anyway? With a gun or something?
This is silly. Bitcoin is about monetary freedom so if you like the idea you must accept that a lot of people will NOT know about your currency and/or will NOT accept it. Hence it makes sense to have bridges between different currencies. A bitcoin-friendly bank would be a very efficient way of accomplishing this.
In a grocery store I pay with dollars coz noone accepts bitcoins. In 20 years the situation will be the same. Because some guys made a bridge between dollars and bitcoins. Because they hid a wallet with coins in a bank vault and gave ppl paper money. Because they made Bitcoin an instrument to store wealth.
