You are a material entity but the set containing you is an abstract
object. There is more evidence for you than for the set.

That is kind of my point. What matters is what is in the set and how we
decide weather the set already contains the object of interest or not.
The set of bids is a lot more tangible then sets built up from the
power set of nothing. ZPC gives us a directory structure with nothing
in it. If I wanted to know if two computers contain the same files, I
would not check to see if the same files are stored in the same
directory.
