"That is, our money has nothing to tie it to reality. It is part of the spiritual world. Today, economists describe money as an “illusion.” "
This I disagree with. What ties our money to reality is that we must compete for it in order to pay property taxes to keep our property. I worry as in times such as these with people losing their jobs, money is harder to come by, and it is harder to pay property taxes and mortgages---for some impossible. This is how the ruling elite in government and the bankers "harvest" wealth away from the people. It is no illusion when your house gets sold on the courthouse steps or is foreclosed. In that sense our debt-based fiat is all too real.
Article 1 Section 10 Clause 1 makes it impossible to pay debts with anything but gold and silver coin. This is why new language has been invented: we don't pay debts anymore; we discharge them with limited liability. Don't ask for references---it's from memory.
I would have added to Art 1 Sec 10 Cl 1 something that makes it impossible for a lender to lend anything but the physical gold and silver coin. That would ensure that he lends what he has to lend and no more with which he could earn illicit interest.
