> Maybe NZ has socialized healthcare? In which case you need to relinquish "personal liberties" to access medical resources.
That argument does not hold water.
Socialised healthcare, as we have in the UK (I'm not sure about NZ), doesn't mean you don't pay for it. We all pay for it in income tax and national insurance through every single pay packet. We also pay for it through other taxes such as VAT and fuel duty.
This means that if, for example, you partake in a risky activity such as driving, and get into an accident, regardless of whether it was your fault or not, if you're still alive but in need of medical attention, the NHS will treat you. If you go out running, trip, fall and break your ankle, the NHS will treat you - even though you could have avoided that injury by staying at home. If you're cycling and you fall off your bike on a patch of ice, the NHS will treat you, even though cycling when it's icy isn't a particularly good idea.
I need to sister some joists in my loft to reinforce them prior to boarding out for storage. If, through my own stupidity, I manage to fire a nail through my hand with my own nailgun (it happens), the NHS will treat me even though such an injury would 100% be my own fault.
Nobody needs to relinquish "personal liberties" just because healthcare is socialised. When we're treated by the NHS, we're getting what we've paid for and therefore (rightly) feel entitled to expect. I am hugely grateful for the NHS, but it is not free, and it shouldn't be making moral judgements about who to treat and who not to treat.
Do I like smoking? No, not at all - it's a disgusting habit that makes you and everything you own stink, and terrible for your health, not to mention a woefully pitiful way to get any kind of buzz or high. The buzz from tobacco is parsimoniously anticlimactic, and it's unbelievably expensive for the minimal payoff in that department. I mean, seriously, at least have some ambition in your vices.
At the same time, do I want to see it banned? Also no, and for all the reasons otherwise discussed in this thread: I don't want to foster an environment in which organised crime can further thrive, and I don't want to criminalise (ultimately) millions of smokers.
This legislation is both a massive government overreach, and a terrible idea.
