Sure, but that is a different argument than what is being sold to the public must comply with series rules, and therefore limits manufacturer creativity, which is the argument the first couple posts made. Heck, one can't even race half the cars sold in the lowest barriers to entry form of racing in America, autocross, which is pretty much open to anyone with a drivers license and a car just this side of a POS.
