Stealing should be illegal in any case. It has nothing to do with labor laws.
> What if your employer wants to have sex with you?
Again. If you don't like prostitution, ban prostitution. It has nothing to do with labor laws.
> You either believe labor laws should exist or you don't.
> If you do, I don't think the answer need to be anything more than "common sense".
Those two sentences are classic logical fallacies. I can support just some labor laws and "common sense" is not an answer to anything.
