Mounting the home (using either knoppix or d-i) requires the luks
passphrase. You could get that passphrase if you're able to install a
keysniffing kernel that my boot loader trusts, and give me the laptop
back. Or perform some other attack that either bypasses luks or
obtains the password.

Booting from removable media bypasses the bootloader (does it
bypass UEFI?). Therefore it is enough to have a live OS on removable
media, equipped with this keysniffing kernel. But, sure, as Dr. Nikolaus
Klepp writes, it suffices to plug the disk into another computer.
I wonder if this UEFI thingy is anything else than a pure annoyance.
