I agree, and I should have said this, “Money as Debt” takes a conspiracy turn at about halfway. I'm a reminded of Adam Savage's "Do you mean Tesla the inventor of AC power, the genius or Tesla the nut-job?".
I very much liked your explanation in the third paragraph, but under this model what does interest represent? If I step through your logic here.....
1. I believe there is copper in that hill which has a value ( say of 60K ).
2. I ask the bank for 10K to get started
3. Thus 10K has been added to the economy, recognizing that raw materials will be brought to the economy and growing the pie of wealth
4. I go into them thar hills, mine out the copper for 60K.
5. I pay back the bank, who now has 10K actual cash in their reserves, against which they may lend. I have also put 50K of my sale of this copper in their bank, giving them 60K against which to lend.
6. At this point, I think we're balanced in terms of what's been added to the value pie.
7. OK, so what does interest represent? The opportunity cost on the hope that I would find the copper? And, alternatively, say I found nothing in those hills, what happens to that 10K that was created? Shouldn't that be destroyed?
I'm not disagreeing, but I'm trying to understand your model better.
