I don't view "own your own domain name" as an ICANN-exclusive solution. There are alternative DNS roots. If ICANN's administration of the root DNS servers becomes truly untenable, then it is possible to make a switch and end-users won't even need to know due to recursive DNS resolvers. If your domain is a .com or a .net, you are also relying on VeriSign. If your domain is in a different TLD, then you are relying on that registry. Beyond that, most of the DNS roots are operated by organizations other than ICANN. I think that the long history of the Internet and the Domain Name System lends it additional credibility over that of web services operated by companies like Google.
