Why Do We Still Hide Our Socks?

It's simple: because I'm not willing to surrender. We've reached this dismal state of things by accepting an unending series of privacy invasions that, individually, aren't really that big of a deal but in aggregate are disastrous. This would be one of those kinds of things. That we've lost so much privacy already is an argument to fight even harder, not to give up on it entirely.

In any case, I wouldn't use such luggage because I'm not willing to take luggage on an airplane, and haven't been for decades. I ship my stuff ahead via a parcel carrier. Privacy doesn't enter into it.

Sounds like something that quickly becomes mandatory if you want to get through security. And would transparent luggage "do" anything? Scanners aren't looking at your luggage as if it was transparent ...

I don't think the transparent luggage is a solution exactly, the issue is we already have security theater and I'm not sure we're any safer because of it.

More process, more / different lines to stand in, I'm not sure that's better.

When I was working for a startups in L.A. I was staying in a hotel that had rooms with glass front walls that had curtains. I used to just leave my stuff all around the room when I stayed in a hotel but at this place I wanted to contribute to the scene which mean keeping my room looking clean, putting all my socks and stuff in drawers so I could leave the curtains open and people could see the nice room.
