The primary argument against that is that it puts strain on society to provide for people when they experience health issues from that. I have paid my entire life for social health programs and health insurance though, why? So I will be nannied until the age of 90, eating only approved healthy food and doing no activity that may be in some way risky?
If we are going to ban dangerous things which people do for no reason other than they enjoy it, should we go after scuba diving and mountain climbing too after we ban Snickers?
