The vast majority of the population will do a worse job on the availability and security of a selfhost solution than 1Password, whose core business and value proposition is password management.
I’m a very happy user of 1Password for Families and consider it the likely the best ~$50 a year that I spend on hosted technologies.
Whether or not you can import them into something else though…
I don't trust many people to do that.
I have everything encrypted and self hosted and I sometimes wonder what I would do if I was suffering from amnesia after an accident for example. And having a note somewhere telling me I have a safe in bank X is the only solution I have found.
Huh? There's plenty of already existing legal ways to do that. Just leave your key with your lawyer or a notary, and existing regulation about fiduciary duty handle everything just fine. You can also make normal private contracts that stipulate fiduciary duties, courts will enforce those contracts just fine.
As a technical alternative (or augmentation), you can also use a threshold secret sharing mechanism to store your keys amongst your friends and/or with companies.
Now what you can complain about is that there is no convenient way to do all of this. And that's a very legitimate complaint! Convenience is important.
However, the way to get convenience is not via regulation.
