The firewall is a conjecture. If you want to avoid this violation of
quantum monogomy (a bad term IMO) you then assume there is no transition
across the horizon once this violation starts to happen at the Page time.
Of course this will not happen all at once and at half the black hole mass,
at around 90% the lifetime which for a solar BH is 10^{67} years, there is
a transition where the passage across the horizon is problematic. This lack
of transition means by some means everything that reaches the horizon is
demolished. The horizon in a sense is converted into a singularity.
