That is explicitly called out in the article and I do not agree with you. Useful information is replicated, less useful information tends to die out. That we threw away that concept entirely in the digital world without a good replacement has some pretty strong downsides from my experience.

And if you read what I wrote in more detail you can see that I'm very open to the idea of soft deletes and intentional information hiding.
