Something still has to locate the resource you want, and that will involve something equivalent to DNS.
replySure but it's a different game if instead of finding the machine that has the data, it can find any machine that has the data. That machine might be elsewhere on your lan or elsewhere in your city.
replyBut that's not how DNS works. It does not find /the/ node that matches the host element of the resource. It finds a list of nodes (often a subset of eligible nodes).
