I would say the issue isn't where to put the line but the fact that a line exists. For example hospitals are required to administer emergency care regardless of the patients ability to pay. Society continues to allow the consumption of tobacco when there is absolutely no health benefits from doing so yet the system will help pay for health complications arising from said consumption.Sure, that is the slippery slope argument. But who gets to decide where the line is? Today must wear a helmet, tomorrow no motorcycles allowed, next week no cars either, only mass transit. Yes I know this is hyperbole but you get the point.
BTW I hate motorcycles. I don't want to be the one involved in an accident caused by there weaving speeding stupidity. But I am smart enough to understand banning something I don't like makes it easier to ban something I do.
The loss of wage earner is the telling one. Clearly proves were all just considered serf's to the system by TPTB at this point anyway.
These are tradeoffs that society makes because we all do dumb things during out lifetime and those things can have a negative impact on others.
