But I prefer a national set of laws that reflects my values.
No, too inefficient. How about a local set of laws you and your peers and their businesses all agree upon? That way you're not getting in the way of people you've never met before, nor will stupid laws like "ban alcohol" or "cut off a lady's clitter" stretch very far.
You have no morality.
Female genital mutilation is an abomination. The idea that the local majority can hire their own police force that will allow it disgusts me.
I am not personally obligated to right every single wrong in the world at my own expense. Those who are concerned about this evil should apply their own resources and manpower to do something about it. While I might be said to "allow" some evils because I am not personally giving my wealth or time or efforts to fighting them, I would also be "allowing" you to use force to do something about it, because I certainly wouldn't stand against you.
Personally, if I'm given a choice, I would be a lot more likely to give my efforts and wealth to help people escape from jurisdictions where these things are allowed to jurisdictions where they are not, rather than to efforts to try to go in to use force to stop such wrongs, which I consider to be a little bit impractical and utopian.
