You just want all your little worker bees to be in massive towers like Hong Kong, without a chance to even grow their own vegetables or have any private space?
I'm not sure if you realize this, but there are a lot of housing options in between suburban sprawl and high-rise apartment buldings. Like townhomes, rowhouses, duplexes, low-rise apartments, or even single family homes built more closely together.
Should everyone have a hydroponics room? Even a basic amount of veggies generally require more land than townhomes, rowhouses, duplexes, low-rise apartments can provide.
