> Why would anyone care about something like this ...
Because it is a dangerous addiction [1] with recognised adverse effects on human health. Like sugar, tobacco, or drugs.
Lets do the nanny state!
(As I get older, unironically. I want my productive worker bees to be drug free, addiction free, enjoying simple pleasures that do not put me at risk. They pay Social Security. Everything is nice and safe. Freedom? Yeah no thanks, get to work and pay your taxes.)
While I agree it's not a net positive, I find it dangerous to equate all addictions.
