> We don't regulate companies to prevent "the worst of the greed" except by some naive definition. We regulate them so they mop up or don't leave messes in their wake, be these messes social or environmental.

Those messes are the worst of their greed that I was referring to. I have no idea what your objection is - that those laws didn't "mandate companies behave good", but merely "readjusted incentives to avoid undesirable outcomes"??

Of course laws are not as simplistic as "try to do good, avoid doing evil", but that doesn't mean that is not their aim.
