Ok wait, I see what you are saying and you are quite right.
My perspective is that in the case of e.g. sqrt(-1) the "territory" does not exist. There is merely the map that is inside our heads and that map can be used to correctly predict real and observable things that happen in reality. The things that happen in reality should not be mistake for actually being sqrt(-1) though. They are merely observations that are predicted correctly by the map most of the time.
I don't think sqrt(-1) exists independently of the hardware (brains) to run it.
Bryan and I took the other conversation off list so as not to bore people. I would be quite happy to do that here as this is very OT!
