I have no problem with bigamy, either. If you’re dumb enough not to have learned your lesson from marrying your first wife, and go ahead and marry a second or third, then you deserve that living hell.
It’s not my business.
Control the borders, keep the courts, post office and highways in proper working order, mint the money, float a navy, and kick enemy ass from time to time - I don’t need the government to do much more than that.
