The instability derives from the "positive feedback" inherent in compound interest acting on the deficit-based money supply. This is mathematically unsustainable and must break down either in resource wars, depression, or both.

It is the "asset basis" that solves this along with the collaborative nature of partnership agreements which make it for "profitable" to collaborate than to compete.

A peer to peer economy would change organically and dynamically, but that need not mean "instability".
