>I think infrastructure will be hugely expensive.
Typically in the scale of millions per year. Which is nothing to walmart guy. The scale of millions to billions is something completely else. When you get into multiple billions it's funny money. Society has rewarded you with so much wealth, society trusts you will use it correctly.
>All these things will be better when doing them collaboratively, instead of individualized. You'll need taxation to pay for them collaboratively.
That's the thing, this walmart guy isn't just paying for all of it out of pocket. There will be people who live and work there who pay taxes to his government.
>But they should be designed and built up-front, before anyone starts living there - because otherwise people will start doing things the wrong way (i.e. traveling by car instead of public transport) and after that it is very hard to change.
That's sort of the thing. The saudis are going to build a long city. When everything is straight, it's easy. Cars will be fine in their design. It's really what your intentions are.
In my design. I have a few things to consider.
The idea will be to generate a new giant city in northern ontario. With the idea of capturing: https://www.mndm.gov.on.ca/en/ring-fire Society needs to start mining that stuff now.
But nobody lives there because the weather sucks bigtime. So we make it a dome city. We at the very same time are designing dome cities on mars. So it's a win in many ways.
>Also: paying for utilities and infrastructure from rising value of land seems not very sustainable at all. It can't cover maintenance in the long run. Many US cities already suffer from that.
I dont understand what you mean here. I suspect you're referencing Detroit as a key point.
>Utopian dreams like these usually do not end well. It took many decades for visionary developments that were planned in the Dutch polders (Almere) to become something approaching a good city, and the results are quite different then the original vision.
this is north america in a nutshell. Virtually everywhere you go there is examples of success, it just takes more than a lifetime for them to become so. Infrastructure that lasts is everything.
