If you are in Canada that isn't really true. It is extremely easy to open a USD denominated bank account and credit card. Couple banks have Euro accounts as well.
Yeah, but if you get paid in CAD, it's still a question of when you want to deal with the volatility—point of sale, or point of forex-exchange-during-account-transfer. You still have to deal with timing it right (possibly waiting months) if you want to avoid losing tens of cents on the dollar.
And if you're already thinking like that, Bitcoin isn't nearly as scary.
Bullshit. And this is not a matter of opinion or speculation. There is data and history. Take a look: http://imgur.com/FmpI0HY
That's the past year. The flat blue line around 0% is CAD vs USD. The crazy red line that's all over the place, swinging by as much as 100% in a matter of weeks, is CAD/BTC.
Unless you're planning on holding the currency, those graphs are irrelevant - what would matter would be short term changes (1-2 days, perhaps). And while USD might still come out better, your graph grossly distorts how this would affect someone wanting to use USD or BTC primarily purchases while holding their assets in CAD.
