Yeah, it doesn't seem likely.

...it needs to be backed by an assurance that the fiat currency will be managed properly.

That's the point of having a global central bank. They would manage it, and we would want to ensure that all appropriate mechanisms for oversight and accountability were in place. Transparency would also be of high importance.

Edit: I should point out that this is already somewhat in place. The US dollar, a fiat currency, is currently the world reserve currency, and it's managed by the US federal reserve central bank. The problem is, the US federal reserve is the US central bank and it is not neutral, nor is it accountable to the rest of the world.

No, I don't want that.

...capitalists will never agree to this.

I think this is the only way the capitalists can make their global, free market work. If the capitalists were smart, they'd want a neutral, global reserve currency. But, since most capitalists aren't smart, it will probably never happen.

We'd want it to be in a neutral place, if at all possible. Perhaps a country would be willing to donate a small portion of their territory so an independent jurisdiction could be formed, not unlike Washington D.C.

It would be best if there were a global union of nations, maybe one with the authority to oversee and manage global trade, as well.

It would have to be issued by some world central bank.

Money doesn't need to be backed by anything, necessarily. Or, I guess you could say money is "backed" by all the goods and services available to purchase.

I've said it before and I'll say it again: the world needs a neutral reserve currency, not one issued and controlled by whatever country happens to be the dominant superpower.

No shit.

I've played a ton of NMS for the same reason I've played a ton of Minecraft: you can build and be creative, and you can acquire and upgrade stuff until it's maxed out. But, once I've built my base and maxed out all my stuff, I lose interest. Fallout 4 also has base building and item customization and upgrades, but there are also story missions and objectives.

Musk has publicly praised the book, 'The Capitalist Manifesto: Why the Global Free Market Will Save the World,' that came out last year. The book, as you would assume, advocates for essentially unregulated, free market capitalism. I think Musk, and others like him, see a second Trump term as an opportunity to try and bring about the capitalist utopia that the book envisions.

If you're a capitalism supporter, this is likely good news. And long may the free market reign. If you're a socialist, well, you better be organizing workers like there's no tomorrow.
