They and the governments are dumbest nowadays, they are destroying the resources and keeping the people poorer, but for what? Then why they want a better rich economy?
The politics is just most the dumbest ideology as there is no philosophy behind anything, Incompetent people are controlling governments, even banks can allow people or governments to exchange such stable assets with dollars and those assets can be kept as a security
I think if governments do it, they can create a tax free economy which can reduce the risk of money laundering, and it ain't necessary that those assets are pegged to a dollar, it can be pegged to a unit of gold (true digital gold)
If the federal reserve wanted a peg to gold, they'd have done it already with normal fiat currency. Obviously they don't want it because they can't freely print money.
Also, do you really think they'd want a tax free economy lol?
