I don't see how this particular irrationality is comparable to the irrationality surrounding NFTs.

To tweak the analogy to NFTs a bit better. Let's say that the fact of the marriage is recorded in a registry, and that the registry is trusted as canonical by the larger entity which people trust, like, the government. Now let's say that the registry is copied word to word, certified to be legal, and then the original destroyed. Surely that doesn't affect the marriage itself, the deep personal bond between the two people?
