You are talking to yourself, not to me because of a very simple reason.
For me the meaning of "what is a number?" starts here:
http://www.geocities.com/complementarytheory/count.pdf
For you numbers are objects that do not depends on your ability
to define them.
For you mathematical objects are actual objects, based on unchanged
logic terms.
For me Mathematics is only a form of communication (a language) that totally depends on our abilities to develop it.
From this point of view Mathematics is an open system that can deeply be changed when its paradigm is changed, and paradigm is not an actual object, but only a theory.
Please read again my answer to Hurkyl:

I am not talking about strings or representations.
I am talking about the difference between theory of x and x.
x=x is a tautology, and this point of view does not distinguish between x and model(x).
Mathematics is a theory, therefore any x=model(x).
By this approach the right framework is {model(x)} so no actual x is involved.
When any x is model(x) no x property has an impact on the existence of the framework itself.
for example:
x=model(nothing)
x=model(something)
or if you like:
x=theory(nothing)
x=theory(something)
In both cases x is a theory of x, and we can avoid the paradoxes that caused by x=x point of view.

The ZF axiom of the empty set does not see mathematics as theory, but
look at its conclusions as actual results, for example:
If x is not empty then x symbol exists.
If x is empty then x symbol does not exist.
This is a primitive and definitely not an abstract approach.
The same is for the transfinite system, that forcing the theory of infinity to some actual object that its cardinality can be captured by forcing "for all" on the theory(=model) of infinity.
When forcing "for all" on the theory of infinity, you have no theory but actual infinity like "emptiness itself" or "fullness itself".
Both states are beyond any theory, therefore they are the limits of any theory.
Shortly speaking, no information can be exchanged between the actual infinity and the theoretical infinity.
The form of theoretical infinity cannot be but "infinitely many elements".
No infinitely many elements can be an actual infinity.
Your precise Math do not understand this, therefore it is using "for all" on theoretical infinity and the result is like driving by using "full gas in neutral".
