Simple exclusion.  Neutrinos can slip through the spaces inside ordinary
matter, because they don't interact electromagnetically.  But they can't
actually occupy the same space as a neutron, can they?

The web (if it could exist) would still let many through - but it would interact
with many more than normal matter does.
