I could sell you a virtual deed to the Golden Gate Bridge right now, you could buy it but it doesn’t really mean anything.
Yeah, that’s possibly the most famous scam in history (people selling deeds to the Brooklyn Bridge), enough to where “I’ve got a bridge to sell you” is a figure of speech for calling someone gullible or naive.
And then despite the world knowing about the Brooklyn Bridge scam, the cryptobros actually went and found a bunch of suckers to fall for the exact same scam, only with blockchains instead of notary seals.
Yeah, that way the community can get inoculated with these ideas and learns how to respond to them, and over enough time the response gets faster and more efficient so that the body as a whole builds up a resistance against whenever those types of comments show up.
