This is a little defensive, you've put a lot of words in my mouth that I haven't actually said.
I absolutely agree you can have stakes that doesn't involve a title, I've never suggested otherwise. The best thing AEW has ever done was the Punk vs MJF feud, and that didn't involve a title, but it was masterfully built and when the match came around it was emotionally charged and almost everything that happened mattered, including the result. The approach this match took was the usual "I want to wrestle X person to see who's better" followed by barely interacting up until the PPV, it's a trap that AEW has fallen into too often. It wouldn't be as bad if they'd found a reason to dislike each other or added some needle after the announcement, but the only thing people will remember from the build is Ospreay taking shots at HHH.
You've also come to the conclusion that I'm saying there's no build because I didn't like it, that isn't true. I really enjoyed the match, I just don't think it was the generational match everyone keeps going on about (I can name a bunch of AEW matches off the top of my head that I think are better for example).
