An interesting question is to what extent people will widely accept first-come-first-served solutions to naming. This is partly the case in DNS but not completely because the trademark system was imported into the DNS in an imperfect way, which means that some trademark holders have been able to use UDRP and/or litigation to seize domain names that relate to their trademarks.

In blockchain-style naming, there's no UDRP, and if you can't get jurisdiction over the particular name-holder, you can't get much joy from litigation either. There's no registry or registrar to whom a court order could be issued.

That has advantages and disadvantages from the end user's point of view: sometimes the legal system would have undermined uses of names that they wanted to make (as in the case of censorship by seizing or canceling a domain name, or transferring it as a punishment for violating an unrelated law), while other times it would have protected them from confusion and fraud.
