I'm perfectly fine with this deflationary concept of existence, and leave the "foundational importance" to particular kinds of existence that actually warrant it. Once its articulated like this I have no problem. But my problem is with those who want to speak of existence of abstract objects in terms that claim such entities are independently members of the constitutive fabric of the universe. I just have no idea what this kind of existence means.
