It's simple: blocks are not built in cities to minimise the footprint like in your meme but to build cheaper and sell more and in the same time externalising the costs of infrastructure development.
A mid density block is something, a heavy packed "bedroom" neighborhood is another.
I'm not coerced, I choose to. I could very well live off the land. The only difference would be the life standard and what I can afford, but hey smartphones, internet and restaurants are a first world luxuries not real life needs.
