Because the current DNS has a single contention point, it is very vulnerable. It can be very easily taken over by a large corporate entity.
The let's design a better system.

As pro-American as I am, this has a certain appeal. No longer are things done for the 'good of the 'net' but for control and profit. At what point do we truly internationalize things that have this vulnerability. Although I think the United Nations is more corrupt than even the USA Corporate/Govt world, maybe some things need to be under control of a multi-nation /government agency recognized by all parties for the good of the 'net. As a socially responsible anarchist, I can't believe I just said it, but it may be a better solution than a Verisign(ish) corporation saying: This domain/trademark is being disputed, and as XYZMegaCorp Corporation pays us $$$ a year for multiple services... you lose. The big problem: a person(s) really in charge of such things that we all would trust explicitly, or at least a reasonable amount.
