One of the best mitigations against rubber-hose and similar attacks is a hardware key. If you leave it at home, you can't be compelled to decrypt unless an attacker also breaks into your home and searches the place.

In a pinch, you might be able to conveniently "lose" your hardware key, or smash it if you hear the front door break open. Doing so effectively erases your data without actually erasing it, since it's unreadable without the key.
