This is the game theory that the Rubberhose file system (co-invented by one Julian Assange) is based on.[0] It's a pity the blog post didn't link to that article, and only linked to the one about rubber-hose cryptanalysis, since this prior art does seem to overlap significantly with the scheme that the post is proposing, as does the Owner-Free Filesystem[1].

Anyway, you're right that the real world isn't a game theory problem, but I do think that if someone is faced with being tortured for information, they should at least attempt to ask the torturer "How do I know that you will stop when I give you the information?". Or, perhaps less incriminatingly, "I don't have that information, and it doesn't matter because you'll keep torturing me regardless".

You may not be able to convince the torturer to give up on the torture (much less convince them to let you go free), but you might at least be able to convince yourself that there is no point talking or trying to come up with a lie. Having said that, it's also instructive to look at the example of Marcus McDilda who was tortured by the Japanese for information about atomic bombs, about which he knew nothing.[2] His lies may have saved not just his own life, but millions more.

Anyone who will torture you for information is going to include this in your torture now, just fyi. Might as well just ask them to let you go.

> going to include this

Include what? If there's some convincing proof that the torturer can give that they will stop, I would be interested to hear it.
