You don’t mind paying an extra $1 or so on each domain name you register do you? Good. That’s what ICANN thinks too. ICANN is the group that oversees domain name policy. Read ICANN partying like it’s 1999 for more on the subject.
Me, I think it’s stupid to charge approximately 10% more for each domain name I register. And I’d love to know more about the 25 cent tax that they have already imposed.
