Right, and the issue here is that Bitcoin is not spendable without first being converted to a better currency that normal merchants like your grocer will accept. That's Bitcoin's weak point, you clamp down on exchanges and suddenly it can't be used with most merchants.

I don't mean to jump between threads here, but didn't you just finish telling me elsewhere that Bitcoin would be accepted once people had no better choice of other currencies to use, and that's why it didn't matter whether or not it was a currently attractive currency for my local grocer?

That sounds a lot like involuntary adoption to me.
