Is it that they're privacy obsessed, or rather that most people have a passion for self destruction and exhibition?

If you think about it, the "dork" position was the one that was most normal, it's the status-quo. The people wanting to record in lockerooms and what not is not the status-quo. They win because most people are short-sighted, or even secretly love hurting themselves.

I don't even care about the privacy aspect, the real problem is that VR glasses are for geeks. This is the kind of thing bullying was designed for.

I block a ton of ads in the name of privacy, and it seems to work out

People don't care about privacy as long as a faceless corporation is doing the spying. People very much care if it has a plausible path to embarrassing or creepy situations involving actual people in your life. The chilling effect of ubiquitous phone cameras is well documented now this would amp it up by a 100. Many cool clubs already put stickers on phone cameras.

i'm as pessimistic as you are, but this is a pretty far leap from key-signing parties and the like.
