You are missing the point that in a libertarian society it is up to the individual to decide what is right for them and not be dictated to by a government authority.
I don’t think the point was missed at all. Libertarianism requires a level of maturity in order for it to work. It has nothing to do with not giving a fvck about your fellow humans, even though most think it does. The way it is applied in the US (disguised as freedom) is pretty poor.
