When I saw this video or this video I thought of this article.
When I feel part of a tightly coordinated and synchronized team I feel proud for the achievements of the team as a whole, which I see as bigger than what I could have achieved alone.
I also don't feel at risk of taking bad decisions. I feel less responsible. If I do what I'm told, I can't be blamed for doing the wrong things. I find it relaxing, every once in a while, to not have to be in charge.
I guess this could be part of the allure of a totalitarian regime: being freed from the burden of growing up
Thinking about this, reading those articles about romantic relationships, I see quite a bit of parallels also with organising cooperation and teamwork.
It looks like I ended up making parallels between Polyamory, Anarchism, and Free Software again. If you think there should traditionally be also a mention of BDSM, go back to "I find it relaxing, every once in a while, to not have to be in charge".
