Do you have a problem with seatbelt laws? I don’t.
We all get the bill for fat asses. How about a law requiring everyone to perform group calisthenics and go for a two mile run every morning? I’m paying the bill for all the fat slobs who eat crap and never exercise. By your logic, there is no limit to government intrusion into people’s lives so long as the camel’s nose of medical costs is going to be used the way the commerce clause has been used in the past century to control and destroy every aspect of the free market in this country.
