What do you do to secure your seed phrases? One Idea...

I have several hardware and software wallets but struggle with how to secure and save the seed phrases. I don't trust safety deposit vaults (my lawyer tells me a court can open one without your consent). Paper makes me nervous anyway, it will burn and if found pretty obvious what it is. Same with the titanium options... it won't burn but but where to store, leave the country - and still sleep at night.

Thinking about keys.casa but like the idea of a totally sovereign self contained bearer wallet - i mean that's the BTC ethos right?

This is what I did..

I have a old laptop that I never connect to the Internet. On the laptop I installed cryptomator.org from a USB drive. I created an encrypted vault and have text files stored by wallet in a folder. I then encrypt the vault with a reallllyyy secure password and then copied the encrypted vault to a usb drive that I store in a few locations.

Where are my vulnerabilities? Any better ideas?
