If the foundation of monetary systems and economic theory is the belief that money is 'scarce', must be issued as 'debt', and must be 'earned' by human labour then true decentralisation will undermine this foundation and bring the whole edifice crashing down. It represents a paradigm shift no less significant than the shift from Newton to Einstein and the rise of quantum physics.
So you're really not asking about the nature of Bitcoin, you are asking Big Questions. I think I grasp what you are seeking. I think you want a new economic model in which all are able to create their own abundance.
Frankly, this is a question in which I have no interest. Not because it is not important. But because I believe it is insoluble.
Here is the central nugget upon which I think you must chew:
Money 'must be' scarce, because the things that it purchases are scarce.There are quite a few corollaries that flow from that seemingly simple statement. But I'll merely outline a couple aspects to ponder.
Society enjoys what limited abundance it has due to the fact that laboring for a wage is what leads to production of goods and services (i.e., wealth). If each person is free to create money (presumably in unlimited quantity?), for what reason will anyone labor? But no labor, no stuff. Problem.
If unbounded money is chasing after a certain item, whose money will be accepted for that item? Why does that person get the item, while everyone else is left grasping air?
On that note, I'm out. If you solve it, you're a better man/woman than Satoshi - whom I think gave mankind perhaps the second most important invention within my lifetime. May whatever god you ascribe to be with you.
