Well one thing it helps combat is link/data rot (assuming that blockchain stays up of course). Meanwhile on our current web, data is disappearing all the time. Like this recent study on the links on NYT articles:
"Predictably, it found that, as time went on, links were more likely to be dead: 6 percent of links in 2018 articles were inaccessible, while a whopping 72 percent of links from 1998 were dead."
