And once we're all on mandatory government healthcare, how does that reduce the incentive for the government to dictate the exact same policies (vis a vis 'penalizing the smokers, the overweight, the gun-owners, the non-conforming') under the guise of "Well it's cheaper if we do it..."
Bonus, there's even MORE motive (of the 'means, motive, opportunity' triangle) for them to continue turning the surveillance state against ordinary folks to find out "who's actually smoking and lying about it to their doctor?"
