The residents in EPCOT would have been renters, so the ideas of evicting for nonpayment, or the landlord doing remodeling and upgrades, seem pretty banal.

Separating vehicle form foot traffic is a strong feature of modern urbanism and even the buried road network doesn't seem prohibitive, if done on greenfield. But it is a rigid concept, that would expose you to immense costs down the line, as the city grows and tries to adapt to changing reality.
