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.  

 That's true. We could just fly in supplies. 

 Or just grow its own food and generate its own power. Sure, trade is generally good, but not reliance on said trade.  

 Lol. I like these discussions. LOL! We can always count on Stella! 🤣 

 Sounds like the shit I deal with on the regular with muh fiat job. Call me when you got a challenge. 

 Fair enough.
