I... guess, but by the same token if we didn't have them, that's not how things would be set up, so we wouldn't need them.
Sure, but way back when, they do seem to have been a necessity.
If the town of Bumblefuck needs a new bridge, then the Bumblefuck city council votes on it, appropriates the money, and pays someone to build a bridge. Why should that be a state matter?
If Bumblefuck cannot afford to build the bridge, but the towns on both side rely on transportation through Bumblefuck, and the larger community relies on those two towns succeeding, then some governing body need to get involved to get the job done. It
could be the Feds, but maybe not. There's gonna be some limit where things are too small for the Feds and I'm not sure that includes that everything below that as being capable of handling it. I'm not sure its true that anything that can't be run from the top can, in fact, be run from the bottom.
Sure we can. All it takes is an eraser. Really, there's nothing simpler than getting rid of states and counties - we close out their governments, invalidate all their laws, and pass whatever Federal laws are necessary to prevent (for instance) murder from suddenly being legal. Easy, at least conceptually speaking.
Yeah, but if that would fuck a bunch of shit up then, as you later say, we couldn't really fix very quickly. That's why I say that we
can't really just erase them. It'd need to be a long and drawn out process to actually work. Although, as you also say, drawing it out would cause it to be denied.
