Making something illegal for an arbitrary group of people is hugely problematic, no question about that. On the other hand, I understand the intention. I wonder if the same could be archived by moving the threshold slower than the speed with which people age. Currently, the age threshold is increased by one year, every year - which effectively locks people born after a certain date out forever. Instead, you could increase it by one year, e.g. every two years. This would allow the next few generations to cross the threshold eventually, while still "aging out" smoking in the long term.
