I was recently intrigued to learn that only half of the respondents to a survey said that they used disk encryption. Android, iOS, macOS, and Windows have been increasingly using encryption by default. On the other hand, while most Linux installers I’ve encountered include the option to encrypt, it is not selected by default.
Whether it’s a test bench, beater laptop, NAS, or daily driver, I encrypt for peace of mind. Whatever I end up doing on my machines, I can be pretty confident my data won’t end up in the wrong hands if the drive is stolen or lost and can be erased by simply overwriting the LUKS header. Recovering from an unbootable state or copying files out from an encrypted boot drive only takes a couple more commands compared to an unencrypted setup.
But that’s just me and I’m curious to hear what other reasons to encrypt or not to encrypt are out there.

Ah lol sure. It depends on what level of state repression you’re looking at. Regular cops will just not bother trying to decrypt a drive if they don’t have the password and you don’t freely give it up (you have the right to refuse to provide a password here, it’s under the same kind of principle as having the right to not incriminate yourself), but I’m sure military intelligence etc will go to the wrench technique. Also deniable encryption for anything particularly sensitive is good for the old wrench technique.
