Anskom's Argument for Self-Legislating

Kant says that morality can involve our relationship to completely external command from a god because then it ceases to be morality. And so Kant wants to say, well, actually, we must be self-legislating, both epistemological and morally. This is something that Anskom finds absurd because he thinks that following the law necessarily involves doing it out of fear. That doesn't even work that way in a system of actual laws in a country.
