You've listed a load of examples where fouls lead to penalties and said "same thing." But it's not the same thing at all.
Every foul you mentioned the trip, the keeper clattering someone or a shirt pull involves a player making a decision. They chose to do it. They got caught. Penalty. That's fair because you're punishing a choice.
Now tell me: when does a defender deliberately handle it in the box? Other than stopping it going in the net, the answer is never. Why would he? The downside is catastrophic. So every handball penalty is punishing an accident. Physics. A ball hitting an arm that's there because humans need arms to run, jump and balance.
And you're right, we don't know if Wood was about to score. So we're awarding an 85% chance of a goal based on something that might have happened. If that cross was sailing over everyone's heads and clips an arm on the way through same penalty. If it was going straight to the keeper same penalty. The punishment is identical regardless of the actual chance of scoring.
"Unnatural position" it is an arm. Every position is natural when you're an athlete mid-sprint tracking a runner. Arms move. That's what they do. VAR has turned this into a frame-by-frame autopsy of something that was never meant to be analysed at that level.
The original law was about cheating. Deliberate use of hands to gain an advantage. Now it's about whether your elbow was 3 inches too far from your torso while you were jumping. That's not the same sport.
And giving an 85% chance of a goal for it? Madness. Indirect free kick for accidental handball, penalty for deliberate. Done. The law is garbage, and 3 high profile games this week have underlined that.
