As Neo pointed out, you seem to be assuming the answer to your question in your argument (that if you cannot observe the number it ildoesnt exist). In any case the number as a description is not dependent on the subject. It is describing an external part of reality, not giving information about the person who holds the view.
No. Counting external things is describing an external reality. That is using a *mathematical model*, albeit a very simple one. And such a model may or may not be appropriate for any given physical situation. Whether it is or not is a matter of observation and testing.
Please define 'a number as a description' in a way that does not depend on the subject. You make the claim that the number 4 is objective: that it doesn't depend on context or the person using it. I have pointed out a few ways in which it *does* depend on context or the person using it.
