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

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
https://bitcointalk.org/index.php?topic=770.msg9074#msg9074One night I had a dream that Satoshi Nakamoto himself came back from the dead with his verified PGP key to provide a sign from above that Monero was the one true coin to rule them all. A voice thundered from the heavens, "Monero is my beloved coin, listen & take heed," with Satoshi's PGP key signature in the clouds, and a white dove came forth and perched upon the fluffy pony's shoulder. With Satoshi's blessing the XMR price skyrocketed to $3,141.59 per coin, and the trollboxes of the earth went nuts. Then I awoke and behold it was a dream...
