That's more or less how yahoo! directory worked (obviously not at the DNS level), however, google showed that crawling the contents and indexing everything, while certainly a lot more complex, it is a lot easier to use. So, while that idea is probably better and more discoverable than the current DNS system, it seems more likely to me that the replacement for DNS will be free text search. At some point, browsers will finally manage to get rid of the address bar and have everything working fully operated via suggestions/search. Then, DNS will become sort of irrelevant for the web.
