Interesting take. I don’t feel this at all. I mean, think of all the poor, homeless, crack heads that are allowed to exist among everyone else in the US major cities. Additionally, a little bit of segregation may be healthy (and when I say this, I don’t mean restrictive segregation by any means). People are meant to be different, and it’s natural to trust people who feel similar.

My interpretation is that “permissions” are needed more and more for online communities (how many followers, who follows you, do you have hot pics, are you non-disruptive in your interactions, etc.) and less and less irl. 

Money & sex rules in real life, for better or for worse. 

I’d also like to note that It’s completely open in online gaming. Some of my best digital interactions have come from cross-play.
