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.
