Just ignore the laws you don't like, according to you they don't mean anything anyway, and can't change what people want to do.
The vast majority of laws have nothing to do with morality, anyway, they only exist to exert control after the fact.
Cut down a tree in some places without a permit? Is that immoral if it is your property, and your tree? It is illegal in some places, though, no matter if the tree threatens to destroy your home.
Is it immoral to wire your own security light on the front of your barn? In many places it is illegal. You can be punished for doing something which is morally neutral, because there is a law!
Granted not all can, not all desire to live morally, and many will not live a moral life, even with legislation to that effect.
Fear of the law will restrain a few, but Fear of God or even just the natural repercussions of their actions will restrain more, if they are so inclined.
You continually confuse small 'l' libertarian with Libertine, and they two are not the same.
Moral does not equal Legal, either, otherwise we would not have legal decisions like Kelo or Roe.
