I think you are 90% wrong, saying money will never be backed by gold again.
Every time the World Reserve Currency switches countries, it is backed by precious metals. 100%.
The next World Reserve Currency is already here, and already being used. People who are not world-class banksters are not able to transact in this currency, but it's called the SDR, "Special Drawing Right."
The U.S. PetroDollar is already done - it's just dying a slow, cancerous death - rather than having its' head chopped off and dying quickly. I would say that the transition from USD to SDR's is already about 40% to 50% complete.
The current process of changing the World Reserve Currency is, I think, being purposely hidden from the common people. The last thing that governments, banksters, and global corporations want is for everyone to have open access to their books, for which they would have to be accountable for.
So, they are selling everyone on how great crypto is, and how great blockchain is - but they, themselves, are buying $#!t-tons of gold bullion as we speak, and they have been increasing their gold bullion purchases every year since 2010.
If you don't already know, the Bank of International Settlements is The World Central Bank, for all national Central Banks. And, on April 1, 2019, the BIS just re-monetized gold bullion, to 100% cash status. In other words, they put all of the big banks in the world on notice: they want to know where the gold is, who has it, how much, and why are they doing this now??? Is it because precious metals have no use as a monetary instrument??? I don't think so!
I'm not negative on cryptos, but I do have a healthy respect for the fact that they are on a blockchain which every government on earth has a very keen interest when it comes to taxing the hell out of the common mans' profits.
If you think that governments, banks, and corporations are going to be forced, by blockchain technology, to lay their financial books bare to be accounted for - I think that's dead wrong. Cryptos will be used as a sort of, "final financial solution," whereby every bit of money that is earned or spent will be kept track of and taxed. That's why we keep on hearing all of this noise about, "The End of Cash." Governments can not tax or keep track of all cash transactions.
Plainly put, Gold and Silver is money, it is cash. It is accepted in every country in the world, where it can be exchanged for local currency. As long as there has been money, gold and silver have been used in this capacity.
The best thing about owning your own stash of gold and silver bullion is the fact that you can dig a hole in your local forest, bury it, and save it for a rainy day. No government can keep track of you that way - and the last thing a government wants is for you to be able to buy & sell things without paying your taxes.
Personally, I have been using crytpos to buy more bullion - which a lot of crypto people have also been doing.
Because, ultimately, a good life is about being free to do what you want and live your life where and how you want to - not where the government, your bank, or your boss tells you to. I think that there is a role for both precious metals and cryptos to play in the future of freedom and self-determination - but I think bullion is better for promoting free markets, free trade, and freedom of movement (although silver is very heavy). Most people could carry their entire life-savings around in one pocket, if they saved it in the form of gold coins. Why would anyone be keeping their life-savings in a bank or other paper contract, which is backed by nothing but paper? Or electronic codes? The point is to be completely free of government and banking interference in your life, whenever possible.
