I am curious how you would end up in a situation where you wouldn't be able to open a door due to masses of bodies pressed against your door. Does your home open up directly onto a sidewalk?
There was quite a bit of discussions last year when an ambulance called for a resident emergency took some 15 minutes to drive 100-150 meters to get to the patient.
The center of Amsterdam is usually be considerably busier than that. And on festival days you can walk across the heads, but let's ignore those because they are clearly outliers.
