If this video doesn't spell

If this video doesn't spell out that digital money and other currencies that undermine national currencies are the promotions of and uses of international currencies, what else is there to say other than, Why are you advancing the destruction of your country, my country (the United States) and all other countries, thereby streamlining everyone and everything? Why are you cheering on interconnection globally, that is, forced globalism?

Guys, simple is the way to go. You needn't a tutorial on a monetary system to understand its nature -- whether it is global or national/sovereign. Sovereign money is right. What's needed isn't the replacement of a currency or currencies that are global but what is (needed) is the capture of the people who have created national currencies worldwide to destroy them to bring about global currencies, which is a global economy, which is globalism.

Why is this understanding difficult for the majority DPers, the DPers who still champion the entrapment, the enslavement, of themselves and, insultingly, of everyone not them excluding the central bankers?

School's fine. Just don't let it get in the way of thinking. -Me

Study nature, not books. -Walton Forest Dutton, MD, in his 1916 book whose subject is origin (therefore what all healing methods involve and count on), simple and powerful.

No one is FORCING you to use Bitcoin.

This "globalism" argument cracks me up every time.

The problem with "globalism" isn't that things are done homogenously, planet-wide.

The problem with "globalism" is that it is USUALLY synonymous with a lack of choice. Sometimes it also means centralized control over that said thing.

Bitcoin is neither of those things nor could it ever be.

We used Spanish and English Currencies

For the better half of our history. What I mean by that is their minted coins. Means of exchange must be legal, competitive, and voluntarily excepted. A gold standard was an internationally accepted currency. That's why Breton Woods gave the high status of global reserve yo the dollar. International free trade and globalism are two different things buddy.
