yes but he can create better systems where moderation is not controlled by groups of higher privilege. Essentially, from my limited understanding, it is not possible to take away moderation privileges from individuals. Please feel free to correct me on this.
I think even if you had complete control to re-write the Wikipedia system from scratch, creating effective moderation systems is a super challenging. Trying to change the current system given the existing entrenched interest is damn near impossible.

As I've tried to point out elsewhere: Mr. Sanger departed from the Wikipedia project in 2002, and, in the time since, has been openly critical of the project. He really isn't in much of a position to make changes to the project he departed from 17 years ago.
