But actually befriending Hagrid is a decision that would take up a considerable amount of Harry’s time.
Harry’s only human, he can’t devote all of his free time to saving the world. He needs intellectual and emotional cooldown time. But Harry’s also an introvert. Spending social time with people he doesn’t relate to is not cooldown time for him, it’s something he’d need cooling down from. That being the case, being friends with Hagrid would eat into Harry’s productivity time. It’s a transparently bad move, and he doesn’t have to spend five seconds considering it in much the same way that a competent chess player does not spend five seconds considering whether to checkmate himself.
