What can I do about power struggles?

I'm an industry veteran. I happily work, enjoy getting being, because I get to work on interesting things, usually with interesting people, and take them to production.

But I'm sick to death of power struggles. It doesn't matter if it's a tiny startup, a FAAAAANG, open source companies or frankly anything in between - eventually some form of a power struggle leads to a massive change. My current example - has my CTO leaving, meaning pretty much everyone reporting to him sees the possibility of becoming him - meaning different groups are fighting, and aligning to own my team. This is dysfunctional to say the least.

I would just like to work, and keep enjoying my work. I remember ages ago (~1998) a company had written into their contract that anyone could reject a promotion, or a move to another team. Until our company was purchased by BigCorp and issued new contracts - that utopia lead to years of successful products that grew massively financially, and people wise. It led to BigCorp buying us - for the obvious reasons.

So how can I excise these from my life? I just want to work. I just want to enjoy my work, and the people I work with. I frankly have ZERO desire to spend a second of my private life attending another mandatory dinner, or office event. I want to spend time with the people from the office I like - and I want to avoid all of these power struggles, that are basically the reason behind the formentiond mandatory events.
