I was going to write a big long post about shoes vs. not shoes, but as I was thinking about it, I realized why aliens are so often naked. (Like Grays. Not the sort of media where the aliens are naked for other reasons.) They’ve lived in a post-scarcity society for so long they no longer have need of textiles. Because they don’t have companies that exist solely to be profitable. Once a society hits the “we can just tell the matter replicators what I want, so we don’t need money” stage, I thing there’s going to be a resurgence of hand-crafted stuff. Cause people will need hobbies, but after a few generations of that, people might be all, “maybe there isn’t really a need to even wear shoes, besides these knit ones from space etsy don’t really work that well.” And over a few generations their feet toughen up a little bit, and eventually they’re like, “who even needs shirts or pants? We keep our junk on the inside anyway.”
