I don't necessarily think we should get rid of the rules either, but for a somewhat different reason. I do believe that free citizens who a.) trust their government officials and b.) can do so without severe economic stress will generally follow official recommendations without the threat of force. at least, enough of them will follow it that the outliers don't really matter.
unfortunately, we don't have a good system to support barbers, who would prefer not to risk catching/spreading the virus but need the money, or barbershop owners, who would prefer to stay closed but need to pay rent. so I do actually support the lockdown as a somewhat dirty hack to trigger benefits for these people.
