I think because it is simple, governments do often screw people over (usually on behalf of big companies) and so they just connect the dots there, that the government restricts “freedom” therefore no government would be better, because people would be “free” to do what they want without the government telling them they aren’t allowed. Incidentally, a lot of these types are very which probably explains why they don’t like the idea of “government telling me what to do” because what they want to do is very illegal and amoral.
