I wonder how much of that is a compulsion to avoid some form of isolation he feels vs a need to show off, I mean he wants to advertise to the world nearly everything he does short of sitting on the bog and announcing he's about to crown (well OK most of the time) but he has a need to share his location when he's going some place slightly more interesting than the corner store.
Think about it for a second even your most online non cow doesnt advertise every time they cross the threshold as much as Cobes, the most you'll do as a normal humanbeing is something like "Love I'm going the shop for some fags, need anything?" you wont set up a stream to follow your shuffle to the shop, your 10 minutes of mixing various libations together and then a grump stream post event.
He knows he gains undesirable attention to himself, he carry's on doing it despite it never once bringing him something positive... Hell when he records and not streams he get's made fun off, noticeably so.
