Why would people hate if it they can't tax it? Isn't it the government which should hate it?
Well, that depends on how you look at it. Would you be willing to be the only one paying taxes while everybody else used bitcoin? I mean, those who are getting paid with fiat are paying for our roads, schools, and services while those who're getting paid in bitcoin aren't paying for any of that but still have the same privileges of use. It's the same argument that applies to the very rich and their tax shelters. See, some people think that everybody should pay a fair share of taxes.
