When Bitcoin will be universally accepted accepted by Government, of course it will be taxed accordingly. Do you think it will still be as in demand as it is right now, that makes its price higher and higher everyday.
Does the bitcoin community is ready for this?
I think, it will be. But that's quite impossible since Bitcoin is decentralized. But if that happens, it will also be. As a matter of fact, it will catch the interest of more people because it will be legal in countries. So it will still be in demand. The reason why they'd still demand for Bitcoin is thst, they are still earning profit from it and taxes will just be a small amount.
