Well, this is possible, but it will be serious changes so the time is needed for such crypto adaption. On the other hand there are more and more places where BTC payments are accepted, but for mainstream acceptance we have to wait a bit. Maybe some of you don't know, but New Zealand is the first country to legalize salary payments in cryptocurrencies (BTC). I think that is huge step forward.
Its been 10years since bitcoin is created , still it is not yet in the mainstream, many factors needed to be consider before we can see the bitcoin there. Also, goverment will be one of the main reason why , they did not legalize it until now , maybe yes it is good for us because there will be no tax for us.
