It is fun cool history. I would have fun doing the trip with the document, not going to lie.
But this ritual is also Proganda for capitalism. I don't mean that in a conspiracy way --- no one at Yale was like "yeah let's do this it makes finance looks good", but it clearly reflects someone having positive associations about this and the history of finance.
It's kind of like how keeping around powerless monarchs is harmless in one sense, but a cosplay to uphold a classist society in another.
I would not try to go for records with the longevity of either, I would abolish the monarchy and force all perpetual bond holders to sell them back to the issuers.
It’d be fun story and a cool bit of financial history, and keeping it “alive” is definitely worth a few grand every 10 years or so.
