Harry Potter and the Methods of Rationality discussion thread, part 26, chapter 97

palladias

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 97. The previous thread is at nearly 500 comments.

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.

Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25.

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

That's a good point. I also add that Wikipedia says that:

A total of 174,100 tonnes of gold have been mined in human history, according to GFMS as of 2012.

But still, if just a few wizards stole appreciable fractions of the Muggle gold vaults, they would be individually very rich. The same 1000 tons of gold would be a (ETA fixed calculation) 200 million Galleon fortune if owned by one wizard. Therefore, the question is how much gold is concentrated in one place (already mined) and available for stealing.

Wikipedia provides a list of officially reported gold holdings by country. The top few are: US, 8133 tons; Germany, 3391 tons; IMF, 2814 tons; Italy, 2451 tons; France, 2435 tons.

But where is the gold physically kept? Well, Wikipedia says that Fort Knox holds 4578 tons of gold. In any case, a wizard could Apparate to people, ask them where most of the gold is (Legilimency/Veritaserum/Imperius), Memory-Charm to erase the few minutes of the encounter, and Apparate away. If the person doesn't know where the gold is, they can tell you who does know. Start with someone like a bank CEO, unlikely to have magical protection (unlike heads of state), and work your way on - in a day or two you'll find the gold.

How do we know this hasn't actually happened? The gold in the bank vaults may not be actually there. But the wizarding economy doesn't have a known history of occasional sudden billionaires. Lucius probably never even heard about fortunes of more than a few million Galleons.

Hypothesis: Aurors simply put alarm spells in large repositories of gold.

(This may not be widely known, because everyone who realises that muggles can be stolen from does so and is jailed.)

There's another big pile of gold, about 7,000 tonnes, in the New York Fed--that's actually where a lot of foreign countries keep a large fraction of their gold supply. It's open to tourists and you can walk in and look at the big stacks of gold bars. It does have fairly impressive security, but that security could plausibly be defeated by a reasonably competent wizard.
