If you draw those things, the actual land use becomes apparent, and then you have to draw the infrastructure to bring the food in and take the poop out. Eventually you’ll start to see that there’s an enormous amount of land use just for living, it consumes the island either way, and there’s an argument to be made for living like a village (as they do in actual villages) because of the decentralisation of resources and lowering the land use of infrastructure.
What are you talking about. It’s an island. Where are the animals for the kebabs? Where are the “groceries” coming from? How much power does it take for the “single” sewer line? Who said the houses would have a sewer line and not septic tanks? What roads? I’m not arguing for the thing on the left, I’m saying there’s a reason why we have been building villages in village shapes and not in apartment shapes.
