The smarter play will always be to ban bitcoins at a really early stage so people will not explore it because if they do, they'd realize that they've been a fiat slave for so long. When fiat's been prohibited in your country for a long time, you'd probably never hear it from the word of mouth. You can read it online but most of us don't stay online for hours and spend time looking for interesting articles
I tend to disagree with that
As to me, banning Bitcoin at an early stage, when it is yet virtually unknown to wide masses of population, would be counterproductive, especially if you can't force this ban in real life (remember, you should never forbid what you lack the power to prevent). If you are going to ban Bitcoin, you will have to publicize this ban which would only attract the attention of ordinary people (something which you most likely don't want). But since you essentially can't prevent folks from using Bitcoin, you will certainly end up where you don't expect to be. Most governments already know that, so they mostly choose the policy of ignoring Bitcoin altogether (as if it didn't exist at all)
