Luckily the stakes are mega low. If someone makes a poor mod decision, that’s easy to reverse. If you want a team’s members each able to work independently but aligned, then you achieve consensus by other means: front-loading the work of creating a shared understanding such that any independent decision made according to the shared understanding would be stable regardless of which team member made it. Ultimately, this is a process relying on trust and cooperation. If a team member violates that trust or plays poorly with others, there should be a process or result. And what this consequence is should be baked in at the create-shared-understanding phase so there is no excuse for bad behavior within the team and an easy out if there are problems.
