You’ve got it exactly backwards. Committees take away autonomy by introducing external influence. Politics by definition is guiding policy, not acting with purpose within the confines of policy.
committees increase your autonomy because you can participate in decision making that could affect you.
obviously if it ONLY affects you and nobody else, then a committee should not be involved.
The alternative is someone unilaterally making decisions for many people, and where I'm from, that's called authoritarianism.
