No one can act without it interesting them. We are talking about rational beings here. There is absolutely no way any man can act, unless he is interested in doing so. That includes coercion, because the only way coercion can work is if the man wishes to avoid pain, or to live on this Earth a little longer.
If you don't think so, then explain how anyone can act if they not interested in doing so.
Any action fits that definition and you've said exactly nothing.
