Beating someone you don’t like to death with a jawbone is normal human behavior, but fortunately we’ve gotten better at deterring and controlling it with laws. If your standard for the value of a law is total 100% then yes, they fail. Rape, murder, and arson haven’t gone away, but I somehow doubt you’re arguing for laws against them to be repealed.

I hope.

Laws aren’t perfect, but they do tend to improve matters when society at large has decided that a behavior is harmful to others. Sometimes laws get it wrong, and then come under pressure to be repealed or changed. Laws against drug use for example, or laws against homosexuality not only tended to fail, but failed to target people for sound reasons.

There’s more nuance here than just “laws regulating ‘natural’ human behavior don’t work.”
