It sounds to me like this is quite the mindset change that might be difficult to grasp at first. Again, I'm either for nor against this. And I don't have all the answers. I just find it a fascinating thing to think about and discuss. There is no right or wrong point of view to this. It's a discussion.

If everybody got what they wanted, would it really be valuable to be greedy? Again, money would have no value. What would greed mean then? If you could get 100 cars, what would be the point if you couldn't drive them all? To show off? Again, mindset issue. Nobody to show them off to as everybody could do the same, and having many cars would have no real purpose as you can't drive them all at once anyway. The reason people fancy expensive cars is because of the value of them. Not so much the practicality always. Possibly the design.

So, I don't have all the answers either, and I do not know what would have happened. This is why it's up for discussion here.
