Why does Congress (the beginning of far too many stupid questions) admit it has no power over interstate driving, yet claim it has power over intrastate flying? Can one to start an intra-state airline and ignore the TSA?
Interesting question -- Southwest originally was an intrastate airline to avoid the regulation that would have killed it. However, an intrastate airline can't go very far.
