> You have the option with Fiat too - you can get paper currency and store it yourself in a secure location. $10,000 can be stored in $100 bills in as little as c0.03 meters^3.

That's really not the same though. With crypto I can store on a hardware wallet that requires a pin to unlock (and resets after 3 attempts) with a backup seed stored elsewhere (potentially split up in n of m shares). How do I backup my cash? How do I lock up my cash in a similar way?

In addition, I can setup "smart" wallets that require an approval from another person to initiate the transfer. Or forces a cooldown period on transfers. None of this is possible with cash.

You buy a vault or a safe, which you can access with a 'pin-code' (in the fiat world this is called a combination lock). Safes come with two keys, which allows you to keep a backup of your 'secret' elsewhere, and you can also insure the cash inside if you want to pay for a full 'backup'.

In addition, "smart" safes and dual lock safes are available which have two keys, mean you need approval from another person to initiate the transfer.

It's not an exact 1:1, but you can hardly say that you don't have the option of storing Fiat by yourself.
