Physical, tangible assets with not be worthless when currencies collapse. Currencies derived their value from the metals, which were a means of exchange - not the other way around.

Brads and shells deteriorate in circulation at a much fast pace than metals. Though metals also deteriorate.

No electricity ..... no computers ...... Bitcoin is dead.
Precious metal is money.
In times past, salt was money.
Money is physical. You can hold it. You can trade with it. Try holding Bitcoin. Heck, you can't even see it.

In numerous countries in Europe cash, i.e., physical money, is virtually useless as no stores or businesses accept cash, only credit cards & other forms of electronic payment.

I'm not going to debate the pros/cons of bitcoin, but I'd bet my entire net worth that at some point in the not-too-distant future, all countries will convert to a CBDC (Central Bank Digital Currency). It's much harder to evade taxes when every transaction has an online trail.

Be easier to just have a microchip inserted into your arm. If you need something, you wave your arm over a platen that scans the chip and deducts from your total assets the value of whatever you're getting.

I learned what money is when I was 26 years old reading Ayn Rand's "Atlas Shrugged".

Well, this guy is "right" up to a point. If there were something to constrain the market to use Bitcoin, then perhaps some of his arguments are valid. But, his (and my) disdain for fiat currency applies to bitcoin also. Why? In the same way that governments create money out of thin air, just about anyone can (and have) create a new cryptocurrency out of thin air. As of this writing, there are in excess of 17,000 crypto currencies. As you can see, cryptocurrencies are collectively a type of fiat currency with no inherent value.

Food, water, energy, and guns / weapons to protect same are all that will matter when the USD collapses (in the very near future).

Try eating a dollar or a bitcoin.

Yep.
It's also much easier to debank people who don't behave.

The guy quotes Maslow's needs hierarchy without attribution and then ties it to money. Okay then.
