If the states want to stand on their own, that is one thing but you can't take money and be part of a country and not follow the greater laws of the country. It's a fine line and a pretty controversial one in some issues. I agree that states make their own laws but only when upholding that law does not require federal money. It wasn't a huge amount of money and only related to highway funding, if they really wanted to do without it, I'm sure some states could have.
