I believe many things we currently accept as normal will eventually be considered ridiculous. Ask yourself what you do often that doesn't really make that much sense.
My most recent answer:
My wardrobe is full of clothes that I no longer wear. If it were easier, and I knew I could get awesome clothes, I'd happily spend a bunch of money, right now, on new stuff. And I'd get rid of/give away/sell much of my current stuff.
This is definitely taking the analogy too far, but I'd love to see what an Airbnb for clothes looks like.
Disclaimer: Most clothes sharing startups right now will probably fail. I wouldn't want to invest, nor found one.
