I want to say:

Bitcoin is virtual, therefore _you_ create/design your own bitcoin storage, it is just a big number, one that we can encode into 12 or more words, and you can use mobile apps, hardware wallets, paper, metal, to help you, but keep in mind that your keys are "information".

This means that if you lose the information, you lose the bitcoin. It exists nowhere else, it is exclusively yours, but also if it gets leaked, stolen or copied and given to someone else, then it is now theirs too and you might never know it until you deposit a large amount of wealth to it and they withdraw it all remotely.

Despite this, being able to design your own storage is great because... There is no perfect physical form of money. Metal can survive intact over long periods of time, but paper is more disposable. Digital forms of information are convenient, but physical forms are more private and easier to monitor and control.

Different people need money in different forms, sometimes in multiple forms at the same time for different purposes, for varying amounts of money. Bitcoin is malleable enough to serve all of these purposes without relying on trusted contracts and legal agreements that only those of us with privilege can access... Natively.
