One example is the very complex set of rules for specific professions in the US. There's no one-size fits all business licence as there is in some other countries. If you want to, for example, start a moving business you buy a truck, and then you have to register as a mover in CA, and if your client wants to move their stuff to WA you have to register as a mover in Oregon and Washington as well. You may then have to register into a special commercial fee system for using the highways commercially. This kind of thing really shocks the redneck crowd who thinks that if they've got a pickup truck then of course they can move that sofa for $20 bucks.
