Your tone implies you're serious, but I struggle to believe anyone could possibly equate persisting digital media with recalling a memory.

In case you really need an example to elucidate, consider reproducing an image. A scraper can quite literally accomplish that, trivially; a great artist would still be limited in multiple facets of the recreation, such that even one with the best memory and hand would find themselves far short of pixel-perfect.

I wonder how we would regard a person who could reliably perform such a feat whenever he pleased. Would we sterilize him, lest he give rise to a bunch of cute little privacy-invading monsters?

If the feat you mean is to perfectly recall disparaging information they see about people on web sites, we already have people with quite good memories. Irrelevance usually keeps them from bringing up the details of strangers' lives on a regular basis. If the juicy details are about friends or acquaintances, well, it's very easy to destroy one's social position - at least, with non-toxic people - by endlessly and tiresomely discussing other people's misfortunes or mistakes.
