For the years I ran the "One Page Dungeon Contest" (where people submit entries and win prizes other people have sponsored), I created a 2 person association with my wife. It's a way to limit financial liability, of course. That is often a more tangible benefit rather than the "let's all do the work and get together once a year and have some votes" which sounds more like work than freedom. But still, having the option of changing the leadership is something that works in a society where we can't all be hyper-individuals.

The Wikipedia article for Swiss associations gives some context.

«An association can serve as a non-profit organization (NPO) or non-governmental organization (NGO) and this form is used by several Swiss sections of international NGOs such as Amnesty International, and the World Wildlife Fund, by business firms (see below) or by international organizations such as the Fédération Internationale de Football Association (FIFA). The form can also be used by political parties and alliances, such as trade unions.»

The key benefit of a Swiss associations is that it needs just two people and written articles of association. Nothing else. No sending it anywhere, no registration, nothing.
