it's normal for developped countrys like yours or mine to not legalize the use of bitcoin. Because they want that peice of pie you are getting . they can't track your income from bitcoin so they cannot get % from what you are getting by taxes or any other means so they are banning the use of bitcoin so they discourage you to get it and you have to use regular fiat money where they can track what you have and don't have . what you can do is just ignore them and keep doing what are you doing because they cannot locate you even if they wanted to no one can force you on not using bitcoin or any other alts also they could be that they don't know nothing about Crypto-Currency and they don't to deal with anything that they don't know of it's very propable.
The same problem is here in my country, because the government is not interested till now to decentralized the bitcoin and prevail it in the country as a legal currency. Why because the official have some problems. I think you will be better understood what I want to say. They will not be able to print more money and so will not be able to keep in their pockets and accounts. The most reason in my country is only this.
