What does sound money even mean?  Money, irrespective of token, accounts for Our energy added into a system.  The psychopaths in control (who have the "fiat" system running presently) own virtually all the "precious" metals.  If the fiat system falls, and such metals are that "sound" money You speak of, They will still be in control.

They will still be able to buy the things and the People to Their agendas.

We will not be free.

The only way We will be free, truly, is when We obsolete the point of accounting for Our energy added into a system - and that will be getting free energy tech out.  Why account for energy when energy is free and abundant?
