> Can you judge how people should live their lives better than they can?

Me personally? No. We as a society in which that person lives? Yes, to the degree that it affects us. That's why we have public education and vaccination.

If you want to retire to a remote cabin in the woods with a ton of heroin and finish out your days, I have no complaints. If you want to do it such that others need to clean up after you (whether that be garbage on the street or an unpaid hospital bill from an emergency room visit), then you are subject to their desires to a greater or lesser degree. You aren't allowed to have the benefits of society without the drawbacks. That's what civilization is.

Oddly, most of the garbage that accumulates on the streets where I live consists of empty cigarette packs/butts, coffee cups, beer and soda cans, junk food and fast food wrappers, etc. And the hospitals are full of people suffering the consequences of recklessly consuming those things.

It's not all that odd. What society deems is beneficial as a whole is not necessarily what is beneficial for an individual. It's not necessarily beneficial even, it's just what's been decided is. A society without caffeine might be better off, but we've decided we don't believe so for a multitude of reasons. That doesn't mean we are correct, it just means we've made a choice.

Cogs that don't fit get ground down. That's not meant as some dig against modern society, all human groups feature this to some degree. Your prototypical small native american tribe is no different.
