Domains are one of the original “digital assets” and have been established to be extremely valuable. Domains are one of the few naturally scarce digital assets! Artificial scarcity can be made to work (see Cryptokitties) but is at the end of the day a social construct. The namespace is finite, and the desirable namespace is a small fraction of that already finite namespace, so domains have a true scarcity that drives value.
