Ok...so lets look 50 years ahead or even further into the future: What happens when everyone has the ability to produce what ever one needs, wants or can just dream up? How will we attain the resources to print these things...how will we earn the value needed to attain property to live on.

I do see a time, far off into our future, if we in fact survive that long, where we can create or print the resources we need to print what we need...but even 100 or 1000 years from now this idea might very well still be science fiction.

So how to we solve the basic problem? Do we trade the process, designs or schematics for the resources we need?
Sure, we can recycle much of what we have to create new things, even food, but at some point, we'll need more materials.
