Are you arguing that the fault for being on the wrong side of the powerful lies with the people who could have just decided not to be on the wrong side of the powerful?
We're discussing here laws where someone, whether the police or some other authority figure, is going to be deciding whether you're subject to them based not on plain and objective facts, but on subjective criteria - which inevitably, and unaccountably, will include your other activities. They're designed to offer a fig leaf so that you can be prosecuted for something whose punishment is comparatively palatable, without having to acknowledge the actual cause for offense.
Of course one can argue whether any particular law falls in this category, but I think it's difficult to argue that the designed consequences of such laws are the fault of the person subject to them.
