I agree. But you need to define that property. That's what I mean by pinpointing it. Describing what are we talking about exactly.

The fact that we are talking about it, is not enough for it to exist.

Let's say there is a ray of light from the sky. And people start talking that there's a white tower standing on the ground as high as the sky. Everybody knows what we are talking about, it's just that we go there, examine it, and it turns out it's just a ray of sun from behind the cloud.

Not such a great example because a white tower would still be much more clearly defined than the ego is, but that's what came to mind.
