Your argument belies reality, where moderators even on the very large subreddits turn over all of the time.

The oldest moderator on r/news has only been in their position for slightly more than 3 years: https://www.reddit.com/r/news/about/moderators

No, it really doesn't. Both what I wrote and what you wrote can be correct. A moderator on a single big sub can, for example, turn it in a red or blue political direction no matter if s/he is a mod for a week or a year. As Reddit is a Corporation we will never see a democratic style mod selection, but in my opinion it is one of the big changes Reddit needs.
