Again we are discussing the arithmetical realism (which I just assume).
To be clear on that hypothesis, I do indeed find plausible that the
number six is perfect, even in the case the "branes would not have
collide, no big bang, no physical universe".
Six is perfect just because its divisors are 1, 2, and 3; and that
1+2+3 = 6. Not because I know that. I blieve the contrary: it is the
independent truth of "6 = sum of its proper divisors" than eventually
I, and you, can learn it.

I agree. It does not make sense YOU SAYING that "5 < 6 < 7", if YOU
don't know the meaning of 5, and 6, and 7; unless you are lucky when
deciding to say random sentences ('course).
It has nothing to do with the fact that 5 < 6 < 7, independently of you
and me. Just keep silent, in case you are not sure about the meaning of
5, 6, and 7.

If you want, numbers are what makes any counting possible.

It is not because some country put salt on pancakes that pancakes do
not exist there. Roman where writing 8 -3 for us 8 - 2. It is like
saying 3*7 = 25 on planet TETRA. They mean 3*7 = 21, they just put it
differently.
