Logistics are something too complex. Your statement makes me think you’re referring to a scenario with one source of a product and either one consumer area or several ones. In that cass, indeed, a more denser region would make it easier, but the scenario I described consists of production decentralized and closer to consumption, making logistics easier and cheaper, with fewer middlemen.
But maybe I didn’t explain it all very well. I have a couple or articles bookmarked in my pc that I will link here when I have the chance.
I just hope my memory isn’t playing tricks on me, because it so, it’s gonna be really shameful lol.
