If it was lan/wifi/bluetooth/local only then I could see it being kinda neat. Could have a little personal profile page for the people in your immediate vicinity. Could even update it by location. Like a kind of hyperlocal Tinder.

But if this is a WWW page doesn’t it open up individuals to D/DoS attacks? What happens when an angry ex nukes your battery on a Saturday night? I don’t see why hosting from a phone should (or even could) be a thing.

The article doesn’t convincingly establish why phone hosting is important. If it’s a cost issue then wouldn’t it be a competitive loss-leader for an ISP add-on like we had in the past? ISPs used to provide web hosting, email, newsgroups, etc. Those all went away in favor of dedicated providers, which seems like a better model.
