suggest that having decisions made by a group that tends not to care about conservative values like respect for authority, group loyalty, and various taboos is far better than those usually made. This is partly because it would better suit my own preferences but also because each of those differences from the norm tends towards deciding what is best for the group rather than best for the leader or best for signalling allegiance to the leader.

Given that you are explicitly disregarding the group's ethical standards, how are you defining "best for the group"?
