Most governments get their money from taxes. If these become impossible to collect, how will the government support itself? They would no longer have control over any currency. Would BTC taxes have to be enforced? Should an alternative be sought? How can a government survive without money?
I'd like to see people's opinions on anything related to this, as I feel that most forum members are better versed in such themes than I am, and I'm open to what everyone has to say.
A sales tax would make sense. Businesses collect when you make a purchase and send it to the government just like a lot of states do right now.
Your right, if government can't tax bitcoin than will tax the goods and the services you purchase with bitcoin.At this point,government won't have any issue to get the money from tax,but in the future, if probably will exist only virtual currencys they will come out with ways to tax/collect money.
