I grew up poor in the 3rd world. Loan sharks, prostitutes, druggies... that's part of life there.
Honestly, your judging something from a certain position that's pretty obviously removed from ever really being needing money (in poor areas there are a options to get money, restricting those would be blessing to the illegal loan sharks that already operate in most desperate places)
I have to say, if you really ever were in such a situation, you'd be advocating not for restrictions, but for options.
Saying we should restrict it because it can be bad... well you should be arguing about restricting alcohol then... there are plenty of alcoholics. Maybe also restrict driving. And fatty foods. And salt. Maybe sugar? Keep at it.
The critics are 100% right. Sorry to say, but it seems you are annoyed at the sneezing, not REALLY caring about the sick.
