Regarding the quote. I'm not cryptographer, but Andersen said that this quote does not really make sense from the cryptographic point of view, and rather proves that Satoshi was not a cryptographer and had only high level knowledge of cryptography. Real cryptographers would never say something like this

So not sure if this is really a quote that Monero want to use this quote from Satoshi, as apparently it has no sense.

Indeed, to Gavin credit he doesn't say this quote does not make sense, but that this is the 101 of crypto. My understanding is that Gavin refers to the vague "informal" formulation in the quote, not to the meaning of it. The conclusion of Gavin just based on this poor formulation is really stretched though. The quote was actually a forum post so of course it's not formulated as a science paper.
Worth mentioning that the post of Satoshi with that quote also mentions stealth addresses. In a way, all Monero is in there

Please correct me if I am wrong, but this part of the post perfectly describes ring signatures:

As an example, say some unpopular military attack has to be ordered, but nobody wants to go down in history as the one who ordered it. If 10 leaders have private keys, one of them could sign the order and you wouldn't know who did it.
I think fluffypony used a somewhat similiar example in the LTB podcast about a company that had to make a controversial decision (something with the CEO, can't remember exactly).
