Well, perhaps. But feet being out in the open air is a good thing, for the feet at least! I like feet, and I hate seeing them unloved, and tortured into unnatural shapes - but it's good overall if problems are more visible.
As you say, some people can't care for them due to mobility problems, through no fault of their own. However there are many more people for whom harmful fashionable shoes, or excess weight, or busy, stressful lives, or general dislike of feet, or lack of knowledge, or xyz all contribute, so there's many interesting and worthwhile conversations to be had.
Though if it's anything like the weight discussion threads, perhaps that's impossible. We seem to be in phase of wanting to letting it all hang out, literally, but without doing anything about what we see. 🤷♀️
Find a friend who likes feet! If you were in my vicinity I'd happily offer some care. Although I'm strictly functional: think properly shaped footwear, foot file and heel crack cream; not bizarre nail shapes, sparkly polish or scented lotions 🤣
