There are no advantages to avoiding power. One of the big lessons in politics is people will sometimes roll in and mess up your life and it never mattered how much of a threat you were. Avoiding power struggles doesn't let people avoid the consequences. Similarly, avoiding struggles is also bad. If you can't resist someone taking your power, then you don't have any. It is nuanced and it is important to be selective in which battles to fight but there will always be some.
If you do want to be a bystander, you still have a responsibility to make sure that power goes to people with a grow-the-pie mindset and not people who only understand wealth destruction or wealth transfer. If wealth-destroyers gain power, you won't be spared.
