You know, none of that can possibly happen until people vote for politicians that will write the appropriate legislation, and then, if they did, then the problem is solved. See, that's the thing, none of you people think this shit through.
As for 'limiting' the feds, screw that. The corrupt locals are no better. You will just have a bunch of battling little fiefdoms, like in middle age Europe, leading right up to another world war. Travel would be impossible with the resulting border bureaucracies. Do you really want to relive in a pre-civil war USA? Well, maybe if you're a white male, with some property, I would suppose so. For me, there's no time like the present
Shens on "Local ones are no better". The scope of the havoc they can wreak is significantly smaller and more affordable than what can be done at the federal or even state level. They may still be power grubbing jerks, but at least the scope of it is reduced to the point that it doesn't affect the pockets of someone else that they aren't beholden to.
