Richard Chappell, critiquing a piece by Sheldon Richman, argues that the philosophical dilemma is simply irrelevant to politics:
[P]olitical liberty is an entirely different matter from psychological (let alone "metaphysical") freedom. The former is threatened by external coercion, whereas the latter is threatened by (e.g.) internal compulsion. These are different! Even if it turns out that moral responsibility is an illusion, that just means that people aren't to be held morally accountable for the things they choose. It's not a reason to impede those choices (given the usual proviso that they don't harm others).
