I think not all countries have adopted the bitcoin as a currency. In this view, not all have introduced a law that states this is to be taxed. If this is to be realized as a bill then it will be deemed final and all our digital activities will be then exposed. So it will be like when you buy an item you will know that at its price there includes a tax. Even in services, there is percentage of the tax included. It becomes part of our everyday lives that when we will buy water there's tax included. For bitcoin transactions, there will be a percentage of tax per transaction. There will be disadvantage and advantage to it. It will become more legal and part of our every day lives when taxed.
