If I’m a member of a small group who thinks we should do X, and you’re a member of the same group who thinks we should do Y, and the group does Y because you have more power in that group than I do (whether that power is due to greater trust or some other factor; trust is far from being the only mechanism through which informal power gets exerted in small groups), then it matters to me.
And if individuals exerting power over groups (whether through trust or other mechanisms) to cause the groups to implement the individual’s preferences isn’t politics, then I don’t know what politics is, and I’m not sure why politics is more important than whatever-that-is.
