Marc,

Although your wording is awkward it is possible you have a real insight here.

The relationship between mathematics and reality is of course a subtle

one. "Consistency" is a concept that applies to mathematical systems

not to "realities".

There are multiple mathematical systems that are inconsistent with

each other. It is possible that the optimal (in some pragmatic sense)

model of physical (or subjective) reality could involve using

different, mutually inconsistent, mathematical systems to model

different aspects of reality.

However, I see no reason to believe that this is the case, although I

recognize it as a theoretical possibility.
