The problem is not a presumption that government can't ever be good. The problem is that the team you personally think is "good" won't be in charge forever.

Everyone loves enabling broad government authority when people they like happen to be in charge.

Sooner or later, a government that is "bad" (for any possible definition of "bad" that you personally approve of) will someday be in charge. Then, suddenly, enabling all that broad government authority seems like not such a great idea.

I don't think this hypocrisy is as common as you believe it to be. I think the current government is extraordinarily bad - I'm on record calling them fascists and murderers quite a lot - and nevertheless it must be allowed to have this authority. There's no better option.
