Why does Pauli's principle hold? Is it a mathematical principle or a
heuristic argument? And why does the principle break in sufficiently
dense objects which then collapse to form neutron stars?

Thanks for bringing this up Tom. My current favorite physics
interpretation is Information Physics. As a result of your answer, I
spent the week looking for a connection between the exclusion
principle and qubits. It is apparently unexplored territory. The
fruits of my searching are only two:

Wolfgang Pauli's Nobel Lecture, December 13, 1946--(quoting)
From the point of view of logic, my report on « Exclusion principle
and quantum mechanics » has no conclusion. I believe that it will only
be possible to write the conclusion if a theory will be established
which will determine the value of the fine-structure constant and will
thus explain the atomistic structure of electricity, which is such an
essential quality of all atomic sources of electric fields actually
occurring in Nature.

Interaction and Entanglement in the Multiparticle Spacetime Algebra
by Timothy F. Havel, Chris J.L. Doran
The multiparticle spacetime algebra (MSTA) is an extension of Dirac
theory to a multiparticle setting, which was first studied by Doran,
Gull and Lasenby. The geometric interpretation of this algebra, which
it inherits from its one-particle factors, possesses a number of
physically compelling features, including simple derivations of the
Pauli exclusion principle and other nonlocal effects in quantum
physics. Of particular importance here is the fact that all the
operations needed in the quantum (statistical) mechanics of spin 1/2
particles can be carried out in the ``even subalgebra'' of the MSTA.
This enables us to ``lift'' existing results in quantum information
theory regarding entanglement, decoherence and the quantum/classical
transition to space-time.
(end quotes)

My hope had been that an explanation built around systems that are
inherently limited in the information they can yield could explain the
difference between spin 1/2 and spin 1 particle statistics. So far,
the subject itself is the only thing that is information yield
limited.
