That has nothing to do with your original statement. Yes, hospital can lose their special protection but must then be given a warning that gives them enough time to evacuate and only if that warning is unheeded, it loses special protection. But all the other rules protecting civilians still apply (distinction, proportionality, precautions, …). In any case, this has nothing to do with the whole civilian population being stripped of their protections. They still have their human rights and cannot be targeted.
