Things I'd read on it is perhaps it's a natural reaction built in to avoid skin diseases that used to all too common. Speculation of course but it makes sense.

You really get to the lack of self control thing. I'm pretty sure if I was a kid today under average modern parents I'd have been labeled with all kinds of disorders or "on the spectrum" and filled full of drugs and coddled into a useless ball of nothing. When I was a kid (particularly elementary school age), I was really bad in crowds and really shy in social situations. To the point that I'd freak out and want away from them. It would have been even worse but I tended to freak out more internally and not like throw a big noisy tantrum. I also have spells where I can't focus on anything and others where I'm essentially hyperfocused on things.

The thing is while if you look there's some things that still linger, today as a mid-30s adult I've had a solid job pretty much since I was 16, am totally independent and actually contribute in some ways to financially support my parents, can and have traveled to many places world and thrown myself into odd and uncomfortable situations, I have friends I do (or did, virus wimps) things with, but am still totally fine doing things on my own too. I really think people that knew me as a little kid are surprised by it all. I put it all the actual progress on not being babied as a kid. I'm not saying my parents were brutish about it, but never was I given the option of "Oh your poor baby, here we will do anything for you let's get you to your safe space. Be sure you take your medicine today."
