We don't accept road deaths, or smoking deaths, which is why we have ever reducing road speeds, and ridiculous slow points to reduce the average speed of traffic. Smoking will most likely be banned by 2030, with some nations already banning it for age groups. Sugar and fatty foods will be the next agenda. Why, because it all comes down to how much cost we are prepared to accept to fund the health system and aged care vs freedom of choice. You wonder why not alcohol, well at present its widespread use for recreation prevents much measures against it, however the forces are already at work to curb that. Prohibition showed that for drugs of addiction curbing general use when it's accepted by the community is just too difficult for sudden changes.
