Nothing wrong if governments start giving consideration to bitcoin as a global currency. Even with the traditional currency it has got different flaws, so at least can give importance as an alternative or a secondary solution for transaction purposes without restrictions which will help with the growth.
I agree with you, there's nothing wrong about if government will allow or consider Bitcoin as a legal global cryptocurrency. It would be a positive news for all the Bitcoin users.
I do not think so, when Bitcoin becomes a global legal currency under the permission of the government, this field will be more popular and we should remember that the profit from this is very attractive, many people can quit the job and go to bitcoin. Especially young people, a society where young people only focus on earning bitcoin and miss learning, miss the future, the development of a country will be affected, and licensing is not positive news, it is even negative when it means that our profits and operations will be managed by the government, we will not feel free and comfortable
