To my mind,the name utopia indicates pessimism,in the sense that the prefix (u-) implies that.
A new name more optimistic could be pantopia,meaning that the desired revolutionary outcome can only have a global coverage,which agrees totally with the need for a global coverage of universal values like freedom,justice,peace and equality as well as the lack of dogmatism on that length of coverage.
Finally, a pantopia to succeed has to remain unending and continuous for not becoming a dogma, which can result only in dystopia, a totalitarian and repressive world.
The word "utopia" simply comes from the title of Thomas More's book. The word didn't exist before that. The actual prefix is eutopia, but he dropped the e to give it more of a resemblance of a proper place name. The prefix eu means good.
