Increasing of community is always good, more users of bitcoin, more chanses than we will see accepting bitcoins in different countries, but still not sure on this theory
It's not theory since you have some real facts based on what will happen. First of all, the adoption is really a factor for one country to accept bitcoin. But of course it will not take the easy path since government will study first all the associated risk if their people will use this currency.
Using fiat has risk, so same with bitcoin that's why they will have to analyze it first before making such regulations.
