One of the example Gwern brings [1] is a GA as an agent for public discourse and political life, to bring your "set of values" to have an effect in solving society's issues, when you yourself don't have the time or energy to.

I don't think it solves or reconciles with self-actualization, but, from a pragmatical point of view, it offers the promise of extending causally your set of views and philosophies to politics.

Gwern also mentions that it allows to keep "human values" (if the GA truly upholds yours) in the loop, in processes that are to eventually be automatized beyond human's reach.
