No bro, I don't think so.
The government system is not operated by just one man there are many people who will stop Bitcoin from legal tender, my reason for this comment is because the government is not just only one person and there are different sets of people who doesn't wants the progress of each other, then imagine if only one or two persons out of hundreds of people decided to legalize Bitcoin, there will be trouble between them self and it will still give Bitcoin a bad reputation because of the bad misunderstanding they might have. Although anything can be possible as long as profits (money) are involved maybeeeeee the government will one day legalize Bitcoin in the society.
If the government finds out that it can milk money from Bitcoin, they will eventually think of ways how to accept it while not straying from their law. The government adoption can also have the reason you stated that because there are sets of people who thinks that Bitcoin is beneficial to country then the government have to adopt and accept Bitcoin. Things can always go either way so do not remove the possiblities of each side happening.
