I think if it looked as if VAR was virtually never wrong then I would lean to keeping it but....
It's wrong less often than referees. It's actually physically impossible for a referee and linesmen to judge an off side decision.
It's not as if, in the days before VAR, everybody accepted the referees decisions. There was plenty of whining about them and for those people who want rid of VAR, I would say "fine, but don't ever question the referee again".
