This is the exact reason we need to get bitcoin in shops everywhere. I think in weeks to come we will see a huge influx in bitcoin users and media attention. I would be furious if the government stole 9.9% of my hard earned.
I guess this goes back to the question of do you use bitcoin as your checking account or your savings account? If you want to use bitcoin to replace credit cards, debit cards, checks, cash payments, etc, then yes it is important to get merchants to accept bitcoins.
On the other hand, if you treat bitcoins more like a savings account, then no, it does not matter if anybody ever accepts bitcoins in their shops. If you want to buy something, simply take your money out of savings, convert to whatever local currency happens to be in fashion and purchase your goods. In this use case, we should help build up the bitcoin exchange network so there is a quick and easy way to go in and out of bitcoins where ever you are. Bitcoin ATMs would be good for this.
