No, you would need to at least periodically slip from complete satisfaction into an infinitesimal amount of dissatisfaction to have the impulse to act. And, you would, in that example, simply be dissatisfied with the fact that not acting would end up with you losing the position which is making you “completely satisfied”, which would impel you to act. Not feeling secure in your position, and feeling like you have to do something to maintain it, is action just like anything else.
By the way, Roderick Long argued against, how, in Human Action, Ludwig von Mises wrote that the idea of an omnipotent God is a contradiction, using that exact argument, that the omnipotent God simply could act to continue his present situation of complete satisfaction; but I am pretty sure that the argument which I gave above totally explodes that argument.
