How do you eliminate scarcity without resources? How do you make phones without gold and tantalum and copper, all of which have to be mined?
the idea of an oldman is... we all work together as one entity (no matter what skin color, race religion or social class), miners mining to build phones, farmers farm to feed the miners etc etc. all we should care about is, our basic needs, "all accesible" food and sex. but what if we want more? what if i'm too lazy to work to contribute to society even if forced?
talking about Japan, they are one high technology country they have houses made of paper, i bet you dont have it. they have automated suspension hydraulic bridge support deep down the sea, but they continually bombarded by earthquake they are struggling to keep up death toll will never be zero when it hits. moral? earth or venus or both are certainly not "paradise", but there will be oblivion, caused by the destruction of human's hand. paradise is something with milky river in it, grapes tree along the side and we can fly out of nothing if we wish to, and not to mentioned.... "alot of virgins"!

and the oldman's idea is actually just reinveting the wheels, once upon a time, there is no such thing as "money" and then it came into existence, you guess why?
