> People are going to do what they want

Sure, but that doesn’t stop us from trying to influence people in other areas, so why should it stop us here. By this argument we should abolish all laws because what’s the point of telling someone “don’t murder” when “people are going to do what they want”?

Your post makes it sound like you are also against taxing cigarettes or taxing cars with big engines or banning guns since we should not (or it would be pointless) to influence behavior in such ways.
