Why governments in most of the countries do not wish bitcoin to be legal?

If bitcoin approve as legal in every country will there be any impact for users?
I think the main reason for this thing is that Government finds Bitcoin as a main competitor for gaining the trust of the mass people specially when it comes to money, and up to now they can't beat it neither join the Bitcoin since it was very techy and so much limitation for the government for now to understand the whole thing with relates to Bitcoin.
