It seems like you're breezing past the concept of the fallacy entirely.
The value of the doorman isn't the intercom functionality.
People like doorman buildings because the building has a real person with eyes on the premises at all times.
An intercom or automatic door opening system can't deal with delivery people who can't figure out the intercom system, don't follow delivery instructions, leave your package/food somewhere random, etc. And that's only a fraction of the value a doorman provides.
An intercom system won't deter trespassers, petty crime, etc.
As long as the building is large enough, the cost is negligible.
I randomly picked a listing in NYC, 219 East 69th Street. 145 apartments on 13 floors.
Let's say you're paying a doorman 24/7 at $30/hour, that's $150/month/resident.
