Ever hear of black holes?
In its original form, the Pauli exclusion principle asserted that no
two electrons in an atom can be in the same state or configuration at
the same time. The principle has since been generalized to include the
whole class of particles called fermions which include protons,
neutrons, electrons, and neutrinos.
It's not impossible, for example, to stick another electron into a
shell, but it will take a lot of energy. So the Pauli exclusion
principle just states how electrons normally behave, not how they
behave in very extreme environments. In a collapsing star the
gravitational energy is so big that all the particles get smashed
together, despite the exclusion principle.

How strong is the force of the Principle?
As gravity crunches a star's atoms together, the electrons of the
atoms repel and push away from each other. The closer electrons are
crunched, the faster they bounce back and forth to repel each other.
The speed that the electrons can move back and forth is limited by the
speed of light. When electrons need to move faster than light (which
they cannot) to counteract the attractive forces, gravity over comes
the electron exclusion principle. *The amount of force required to do
this is called the electron degeneracy pressure which is equal to the
Chandrasekhar Limit (1.38 solar masses). Anything exceeding this limit
(without usable fuel) will collapse into a neutron star.
The norm for a neutron star with a 12 km radius and a mass of 2.48
solar masses is a density of 20x10^14 g/cm^3 (2.0x10^9 tonnes/cm^3).
It's unclear what exact value to assign to the neutron degeneracy
pressure. *But it is calculated to be between 2.0 and 3.3 solar
masses.
If it is a law it would be infinitely small.

You are treating the Pauli Exclusion Principle as degeneracy pressure
