So it's all demand and everything can be rationalized. If no "needs" all we can say is we demand the current environment. You are demanding the environment stay reasonably like it is now.
When you can't truly define "Need" then that is your downfall. You can't see that there is no true "Need" and only Demand and IKEAs are the result of that. Zen, man, Zen!
What exactly is the definition of need? Do we really need anything? Or do we just demand a lot of things? Are we not truly supplied with everything we need to live?
