Why not? I had this setup for years before switching to bitwarden_rs.
You have apps on every device to access your password database and do autofill. I stored everything in KeePass, recovery keys, TOTP seeds, sensitive documents and notes. I get the password sharing thing for families but for a single user they have the same featureset. The only thing missing is browser access but even though I now have browser access to Bitwarden I think I’ve used it like twice. I think I used Keyweb maybe once.
It's not the same thing because the whole argument being made is in the context of 1Password and its target audience: normal users. That's your mum and dad and other very likely non-techie people.
