Once my mom threw out all the cases for my computer games and put all the disks into a cd binder to save room.

It was devastating.

As people said, you can backup your private keys to a flash drive. You can put them in a safe deposit box. You can give them to your lawyer or other fiduciary with a legal responsibility to act in your best interests (who also knows how to protect digital property if they keep digital copy). You could write it with lemon juice onto the back of the Declaration of Independence at the National Archives. You could have a laser thingie that displays it on a wall surgically implanted into your arm. Pretty much all the ways people protect gold or cash in the real world you can do with a piece of paper with your private key.

You can lose access to regular accounts as easily as to a blockchain. In fact, losing database of your password manager is even worse, because even if you have backups, they're not going to be complete.

With a blockchain all you have to worry is your private key. And you can write it down on a piece of paper, if you want, and put it away in a safe or a bank vault or something. Then, if you use it to restore your access years later, nothing will be lost.

"There are 2 types of people in the world: those who make backups, and those who don't make backups yet."

Not really. You backup you keys like a normal human. Or create any of those new account abstraction keys that are tied to another account, or anything else.
