It's not ideal - we all know that, but I'm not sure about your point about the United v LASK game. What prevented it not translating to TV viewing? It was an entertaining enough game.
I agree, it's probably going to be 2021, before any of us can attend a game, but football - particularly at the higher levels needs to continue.
The Premier League can command TV audiences of millions, so as long as they secure the safety of the players, back room staff and everyone involved in the set up, then they need to get on with it - behind closed doors.
The difficulty is at our level. How do Clubs deal without the gate revenue?
