Its easy to predict that governments wont allow to be outcompeted by bitcoin. They have a money monopoly and thus will prohibit significant competition. Thats different than prohibiting alcohol as the merchant can accept dollars instead. No need to accept bitcoins. However alcohol is something you cant replace. Also alcohol is not where government derives its power from. Money is (inflation to finance its operation). It is already impossible for bitcoin to become a significant medium of exchange due to tax law.
Now regarding store of value I have explained why I think bitcoin is not suitable.
Can the government prohibit me to use, for instance, dollars to pay people (if they agree) even if I am in italy?
Would such prohibition be compatible with the italian constitution? Is there something in such constitution that states that we in Europe must use as medium of exchange only euros?
As far as I am concerned the only thing that government can force us is to accept "state" money in repayment of debts. That is because there is no alternative.

Reread the thread: They force us by expecting us to pay capital gains taxes on every media of exchange thats not government currency.
