Not sufficient, given reports of TVs and other devices automatically creating mesh networks. Your disconnected TV could talk to your neighbour's connected one. If anything, I wonder why LG isn't already doing it.

Edit: Getting pushback asking for evidence (fair). Most recently I read it in an HN thread a few years back. I thought it was a TCL TV, but I can't find it anymore. It wasn't Samsung's WiFi Direct, which I don't think was ever on by default.

Lacking better evidence, I'll admit I'm probably wrong and no TV has been documented doing this (yet).
