Any mega project requires a need for it (either real or perceived) and the funding to make it happen. Unfortunately my Arcology savings account isn't growing the way I'd like it to, and I don't see any place that has a real need for it. A country like Dubai doing it as a vanity project before there is any need for it would probably make the concept into a joke. That said, I'd love to see one built for a good reason.
