No, I completely disagree with you. Having travelled the world, I feel the worst thing we can do is continue with the big cities. They need to be dismantled, and replaced with smaller, lighter, more local communities that do not require so much energy to maintain - very big city requires immense resources to keep it running, every single day. More rural living is what will save us, imho.
Except that is false. A person living in a big city uses drastically less resources and energy than a rural person does. Less/no driving, smaller more energy efficient dwellings (apartment blocks = way more efficient heating/cooling), vastly less infrastructure per capita , etc.
An honest appraisal cannot lead to the conclusion that cities are good for us, energy-wise.
