Laws are what caused this problem in the first place. Government in the area has messed up the free market, and this is the result. Source: https://youtu.be/yiXjiJ5GSoM

I never use my kitchen, why should I have to have one?

Because it's not all about you.

Plus "no cooking allowed" is not about having or not having a kitchen.

Well I admit that I lean libertarian, but I'm curious why you think it would be beneficial to society to constrain choice in this manner. Presumably if units without a kitchen were illegal, then the prices would just be higher to account for kitchens.

Why? Someone probably really wants to live there, if they're willing to pay that much to do it.

Someone also wants to rent out their kids as child labor, and someone will want to hire that kid. Doesn’t mean it should be allowed.

Kids don't have the same level of rights as adults to enter contracts to work. We do it because we accept that child labor damages education potential.

I'm an adult, if I never cook because I like to eat out, shouldn't that be my choice? Who am I hurting by choosing not to cook?

You cannot really be comparing housing without a kitchen in a large city like San Francisco to selling a person, right?

Somebodies also want all kinds of things that make society worse. That doesn't mean we should allow or worse encourage them.

The idea of what's good at large is what differentiates a society from a bunch of people that just happen to share a country and a legal code.

How does choosing not to cook make society worse? That's basically the same line of argument used to shut down gay marriage or other non-conventional lifestyles.

Who am I hurting by choosing to eat out every day?

While we're making overly dramatic distinctions, a legal code that actually means something is what separates a free people from totalitarian 'society'.
