But what are you touching? some worthless slip of paper... it's the same scam, medium doesn't matter. And if the medium matter to you, and you prefer physical, then you should use precious metals because those are market valued.

I've seen a few power, internet and server outages in cashless hell in my days, the modern day world is so dependent on digital stuff that you won't be able to pay with cash if the digital system goes down. Not to mention the huge risk, there's no verification in cash, you have no way to know if it's real or fake.

Plus that any day M$ could release a printer driver update, which would allow any fool trying to counterfeit cash through their home color printer will succeed, that's blocked today by most printers by design but could easily change with the flip of a switch.

Bitcoin and most other large coins are peer to peer, that's the most redundant design a digital system can have. It'd take a global permanent outage to eliminate it, and if that where to happen we'd have bigger issues to worry about anyway. Why would anyone need money, when there's no market? Should the society ever recover from a full collapse bartering will work just fine.
