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.
Using a bank is much more convenient to store Fiat though if you want to buy/sell things, much like using an exchange to store Crypto is much more convenient if you want to trade crypto (because let's be honest, not that many people are using Crypto to buy pizzas!).
The security is based on you remembering a 12 word string or geolocation, and the string/geolocation can't be siezed via court order (other than exceptional circumstances, or by finding the location/keys).
The 'storage' in both instances is decentralised. If you forget your 12 word string or geolocation, you lose your money.
Banks on the other hand:
* Provide convenient and safe access
* Will invest your money (in exchange for interest).
* Allow you to reset your credentials if they are forgotten (by proving identity)
* Are centralised
As time moves on it's clear to me all these assets are becoming important members of the financial landscape. If crypto were merely a degraded version of the dollar, then I don't think so many people would use.
All of those are more convenient than storing dollar bills or gold bars. So, yes, fiat has options, crypto is another kind of option and probably the most convenient for self custody, hence a very good one to avoid trusting institutions.
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.
With fiat, you also have the option of storing gold yourself.
Granted, that would be stupid, but it's certainly an option.
... what do you call putting cash in your wallet?
With crypto I can:
* lock my cash on a device behind a pin (with forced reset after a few attempts)
* back it up in multiple physical locations, and require n of the m recovery locations to be accessed for recovery
* memorize the seed phrase before escaping from an oppressive regime
None of this is possible with cash in my wallet.
