That's not a reasonable definition. The distrust in the institution is actually a side effect of questioning the authority for authority sake. Anarchists aren't a bunch of individualists that want to burn down whatever we've got in terms of mechanisms in the society regardless if they are necessary. It's just the manifestation of the dialectical opposite of the expression of power and authority.
And privacy enthusiasts just know very well that power shifts and what once was a necessary mechanism can be abused by an elected authoritarian leader.
That's a mighty broad brush you're painting with over there.
