A little reminder that Sun Tzu “The Art of War” is not some grand masterpiece in strategic thinking. It is a guide aimed at nobelmen that were so far removed from reality, that they needed to be told things like “You can’t just order a win in a real competition” or “If you don’t give your soldiers food, they become weak and die”
That's not really what the book says. It does go into strategy (though today it's rather inspiration than something to be followed to the letter).
Plus, while you make it seem trivial, logistics are really hard and must not be overlooked. It's like saying "Germany lost the Battle of Stalingrad because they didn't know that if you [edit: don't] give your soldiers food, they become weak and die!" like, they probably knew this, but their strategy lead to a situation where this happened.
