There is nothing inherently evil about 15-minute neighborhoods and cities. It only makes sense to reduce the time it takes to get from one place to another.
This is best achieved by making smart, positive changes that follow a long-term vision. These may include relocating customer-support offices to the city centre, building underground tunnels for garbage trucks & other service vehicles, and generally eliminating the need (not the right) to use a car.
Government-planning, meanwhile, kills people with its arrogance. We must not allow our cities to become district-apartheid mass-surveillance lockdown prisons that coerce us to follow overlords’ demands. Mandatory kill-switches & speed-limits must be abolished, and surveillance satellites removed from orbit.
