VAR in many cases disempowers referees from making decisions
I don't think I've ever quite grasped why this is a problem, or the reasons for protecting the 'sanctity' of the referee's authority (not your wording, just all I could come up with).
Why isn't it just a team effort? Like in plenty of other sports, where there's generally one person making the final calls, but that person gets input from a whole team of officials. I really don't see much problem in "ah, something you missed here", "oh, yes, I did, for I am but human and can't catch everything, especially at breakneck speed, let's correct that".
Offsides are actually a really good example of this. For a human to call it, they have to be watching a) the point of contact on the ball, b) the positioning of the 2nd to last defending player at point of contact with the ball and c) the positioning of the furthest attacker at point of contact with the ball,
all at the same time, at super-quick time, very possibly across 10s of yards. In many situations
that just ain't fucking possible for a human to do. So, bring in additional help.
And yes, offsides have their own problem with the "mm here, or mm there" stuff, but that's just the nature of the rule -
wherever you draw the line, there will be incidents that are a mm either side of it. No way round that, far as I can see.
