I just finished his talk that I posted and he actually goes through alot of technical aspects of censorship in bitcoin. and why ordinals can't be blocked on a network level. That being said his discussion of ordinals did change my mind about how important they might be, definitely just garbage and spam

There's other opinions on that, but I don't have the technical knowledge to comment on it.

I will say though it seems like he actually agrees that nothing can be done about ordinals. They are retarded sure but all you can do is not include them in your mining pool or node.
