That would be good unless you live in states like Crazyfornia, NJ, and Il plus several others.
Well that's the point. It would minimize their influence on the rest of the country. If you don't like the laws of your state, it is much easier to change them at a state level rather than fighting it on the Federal level. Worse comes to worst, you are able to move out of the state. Its a lot harder and inconvenient to up and move to a different country.
Edit: I can live with a state democratically voting on certain restrictions on the 2nd amend. If the majority of the people do not want people owning a howitzer or machine gun, I'm ok with that. I'm not ok with the Federal government who is out of touch with the people controlling such restrictions.
