OK, but we have to distinguish
A) the existence of numbers, and
B) the discovery of numbers by humans.
I can understand how human discovered numbers  by mixture of 
introspection and observation of a physical reality (and struggle of 
life ...).
But to understand the physical reality I need the numbers at the start.

Normally classical comp implies quantum observation, and quantum theory 
can explain the emergence of the classical mind (in the Everett, 
Hartle, Deutsch way).

Comp makes qubit emerging from glueing dreams by  bits. But our local 
bits emerge most probably from our local qubits.
Bit---Qubit is a two way road, if comp is correct (and if my reasoning 
is valid, 'course).
