Without the need to build ships, which is really hard. LOL

That seems impossible, though. An independent city such as that would need supply lines. Of course, this also depends on the location.
Right, cuz the Greek city-states had such short lives.
Sarcasm aside, it's really not hard to set up something like this, it's just not really done legally when da gubment wants a cut and to control everything.
Well, yea, that's why I was saying that the location is crucial. Read about the history of Carthage and compare it to the Greek city-states.
We have better transport tech now. Also, a walked city these days, if it had access to good water, would be pretty easy to sustain itself.
