The city is still a half-born ecosystem, still in development, far from ideal--what would it look like if finished?

That is, a rainforest doesn't need anything shipped in from a desert, and vice versa--everything they need is in the soil, + water and light
So, a city ecosystem might be considered "complete" when it no longer needs inputs *besides water and light* from outside the city
One crucial addition: inputs *from other cities* are essentially inputs from *inside* the city, don't count against the "no inputs" rule
A weird ecosystem; spatially discontinuous, it exists all over the world but is only manifest at specific places in it
This is literally what I believe the telos of cities is--whether or not it can ever be achieved is another matter
