Our debt is to the FED, a private banking cartel. The FED creates fiat money out of thin air. The US must pay it back with interest. The interest must be created out of thin air and borrowed from the FED. It has been proposed that the US repudiate its debt to the FED and eliminate the Central Banking system. It could go back to a precious metal based system - with a block chain component and a Treasury Note component.
There needs to be some sort of transition or reset or debt Jubilee for the economy to recover and resources invested back into a productive free market. Of course, you then have problems with aiding the elderly to live if they are unable to work. A lot of paper wealth would go with the FED, but so would the debt.
You can’t sell a lot of the “Public Land.” It has private split estate mineral, grazing and right of way property rights associated with it. They tried to do that once before. There is also questionable title to the lands (fed or state.)
In regards to the land sell - there are private lands sold quite often with the same split on rights. Timber, Oil/Gas, minerals, etc are quite common to have been leased or sold off. I personally look for this when considering a purchase because I want those rights and don’t want anyone intruding on my land for something I didn’t sell.
As to the fiat money solution I concur with you except the block chain - which to me is just another thing created out of whole cloth that can continue to be created. I think it should be a combination of 6 metals: platinum, gold, silver, copper, nickel and aluminum based on current global ratios + a component for oil/gas + a component for arable acerage. Another way to put it would be non-renewable resources, energy, and renewable resources. still have to watch the formula isn’t tweaked (maybe limit it to once every 10 years or something like that), but at least it would be based on something of value.
