This proposed building has 2 entrances for 4000 people. I cannot imagine it will pass fire code, or could effectively be evacuated in an emergency. Astounding that someone thought it was a good idea.
This idea that a 60 floor skyscraper is going to do opening window "exits" over 300 foot drops is insanity and disgusting.
Please look up condominium skyscrapers before talking about window exists being required from a housing code standpoint.
The usual expectation is total time for a fire to cause an alarm, all occupants of a building to respond to an alarm, and make their way to a fire rated area, usually a stairwell, is 2.5 minutes.
You can have a bedroom with only one exit (the requirement you reference is for a second exit, not a window) if walls/doors are rated high enough and you have sprinklers.
Compounding this, historic building in CA was sometimes very poor by modern standards (all wood tinder boxes). So this may very well be a major upgrade in safety over existing housing stock.
If fire codes were not a thing, developers would build terrible fire traps and people would rent them. There would inevitably be many deaths; this has happened all throughout history prior to modern building codes (and of course still happens today[1]).
The free market is a lie and impossible; you cannot expect the common person to be an expert on everything. We need (and you should want) baseline standards to ensure a reasonable quality of life for our society - think automobile safety standards and building codes.
Not with that attitude.
[EDIT: sorry, that probably comes across as harsh. My point is that this whole site is for people to discuss things, and your comment(s) seem to advocate that people stop doing exactly that]
