Success, and control. This is an unfortunate side effect of our civilization. Out there in the real world, between the laws that protect us, corporate interests that manipulate us, the haves that have more say, the neighbours of which we don't - and can't - know more than 0.1%, the jobs that are so hyperspecialized that not many of us contribute an atomic piece of value to anything - between all that, we find ourselves with little real autonomy. Little influence on the environment. Little space to grow. And we
can't have that, we can't have autonomy and fun, because that would be destructive to the fragile fabric of society. This is the one aspect about progress that depresses me. We're slowly morphing into a civilization-scale organism, where an individual does not matter, and is nothing more than a single cell is for one's body.
(People from smaller towns and villages may disagree; but this is how living in a 21st century city feels to me. It's a wonderful place, but also a straitjacket.)
Given all that, I can entirely understand the kind of escapism that tries to make you feel that you matter, or that you're a part of something that matters, or that you and your friends have some meaningful control over the shared environment, don't have to deal with as many people, escapism where there's no jail time attached to half of the fun things one may do.
