Some YC founders bring their whole family with them. Also, at some point in life, living a dorm starts to sound like torture.

Many women have obvious, easily predicable concerns about sharing living space with unknown men.

Surely you could set up the spaces so that this could be much less of an issue?

Sure. Those are called "apartments".

Yeah, and then you put a couple of people of the same gender together in them…and now they're basically back to being dorms.
