Why should everything be balanced on the backs of the working and middle class if we're talking about architecting a more functional society.

You can believe that "densification" will be applied in-equally as well. Just as it happened to poor or working class folks who were gentrified out of the homes they had inherited, it will move up the 'class' gradient until only the wealthiest own everything.

At some point the practicality of life in a civil society has to trump insane ideologies committed only to protecting 'property rights' of a small minority.
