That's a good take, I hadn't thought of comparing it to Primer. In Primer, it's clear Shane Carruth thought out all the implications of his time travel system. I don't get that feeling from Tenet, where it feels like Nolan thought it would be cool and didn't go further. What you end up with is a movie that's fun while you're watching it but falls apart once it's over and you think about it for more then 5 minutes.

The scene I think is the most egregious is the air terminal fight. It's a cool idea in theory but a fist fight between two individuals going in opposite directions in time would immediately result in a paradox. It's hard to explain but it essentially boils down to the fact that both fighters are reacting to their opponents reaction to the move they're about to make.
