What exactly is not holding up that robust lunar crust?

Moon interior open space as geode like hollows/voids w/air at 14.7
psi:
14.7 psi = 10.335e3 kgf/m2 (x 6 becomes a force worth holding up 62 t/
m2)

Exterior Vacuum at 3e-15 bar = 1.2e-12 inch h2o = 3.06e-15 kgf/cm2
Otherwise a negative pull or suction of 14.7 psi (10.335e3 kgf/m2) =
62 t/m2

Assuming this mineral saturated lunar basalt is that of a sufficiently
fused molecular kind of solid that’s only leaking sodium, whereas
1/6th gravity should become worth 124 tonnes/m2 of holding that lunar
basalt shell up/away from the porous or semi-hollow mantel and its
tidal offset core, as such is going to lift or hold up a serious
amount of that basalt crust per km2 (124e6 tonnes/km2), not to mention
whatever interior pressure below that thick and heavy crust should by
rights be something considerably greater than 14.7 psi.

Due to the crust porosity and various mineral leakage as having
allowed some degree of subsequent pressure/vacuum equalization,
whereas even I might doubt that we’d get anywhere near that kind of
result, but it’s certainly fun to ponder.

Seems it’s going to be a little tough for our moon(Selene) not to have
those cavernous hollows/voids of some kind, at least a few solidified
geode like pockets, porous layers or accessible vugs within and under
that extremely thick and robust basalt crust, especially where that
supposedly iron core has shifted at least several percent (25%)
towards Earth in order to help offset that much thicker and mascon
saturated farside crust.

The farside mass offset of this unusually heavy mineral saturated
basalt crust is worth 4e21 kg, and the maximum 450 km radii of the
metallic core is supposedly worth 45e21 kg (more than likely it’s
only worth 4e21 kg). Therefore this dense metallic core of supposed
iron needs to be considerably offset towards Earth, so that the
greater proportion of lunar mass is always facing Earth.

Not that any thick and mineral saturated form of fused basalt crust is
ever going to easily collapse under it's own mass, especially not at
1/6th gravity (even less gravity below that crust), and of course
better yet if the average interior atmosphere of whatever pockets or
voids of gasses were 100 bar (1470 psi) shouldn’t be unexpected.
