Try tabooing exist: you might find out that you actually disagree on fewer things than you expect.

That's way too complicated (and as for tabooing 'exist', I'll believe it when I see it). Here's what I mean: I see a dog outside right now. One of the things in that dog is a cup or so of urine. I don't care about that urine at all. Not one tiny little bit. Heck, I don't even care about that dog, much less all the other dogs, and the urine that is in them. That's a lot of things! And I don't care about any of it. I assume Eliezer doesn't care about the dog urine in that dog either. It would be weird if he did. But it's in the 'everything' bucket, so...I probably misunderstood him?
