The problem is though they are different things
offside is objective you either are or you aren’t (although personally the minute cm ones should be onside)
penalties are subjective for the most part - and VAR isn’t suppose to overrule it is looking for clear and obvious error - so there are rules which can be open to interpretation and if it is the case that the referee made an interpretation that fits the rules that cannot be overruled or overturned
you cannot get 100% consistency in a subjective decision because it is well subjective!
what is ruining the game is the drive for consistency and every decision being correct when you cannot achieve that with subjective rules.
a time limit is completely necessary and then trust (like we did for years) the onfield decision
goal line tech though is always required for the ball that is 100% accurate
and Bodo are out which is a shame still they can be v v v proud of whst they achieved
