VAR uses the wrong system.
It's relatively easy to fix it: set it up so the VAR is the same person as the match ref. That way the accountability stays in place: the ref only overrules themself with the benefit of video and can do so in any way they see fit.
If the ref elects not to review the footage on a bad decision, that's on them, but they can take advice from assistants or a match committee as necessary.
VAR is then just the solvable technical problem of swiftly providing the match ref with high quality, multiple angle footage out on the pitch.
That's not easy, but it has tremendous advantages over giving a Liverpool fan in a broadcast cubicle somewhere off the pitch, a person most watching fans wouldn't be able even to name on the day, the authority to send players off.
The main issue left would be the other one we've got now, reducing disruption.
