If you're in the middle of nowhere, with your small loving tribe, and don't know much about whatever ongoing genocide and needless destruction, or about capitalism and the depraved, Diddy-level hedonism, you might sleep better at night than those who do but also feel powerless to change it. What about having terminal cancer? Wouldn't it be better to just live your last days in happy ignorance? Information is a double-edged sword, basically, and when you know A, you hate A and you also 'know'/feel unable to change A, it's just poison.
