You are conflating two issues. One being there’s no quality on linear TV (when there is) and the other being TV companies will (I would say “may”) have to produce more of their own content.

TV companies around the world will be in exactly the same boat in your post apocalyptic dystopia. There will always be scope to pool resources or buy from independent production companies.

All the “good stuff” going to streaming is entirely subjective. You’re also ignoring that Comcast are a major content owner distributor themselves.

Game of Thrones brings up something else though with this being considered a significant series drawing to a close worldwide and everyone engaging with it at roughly the same time.

Something that will be lost if series just get dropped in one go due to the entire audience watching episodes at different rates. A subscription tv series may never be as talked about it as popular again.
