That's a fair point, however, action has often much clearer short term consequences than inaction, and the consequences of inaction can be studied at leisure because action always is still an option. But once you've done your action thingy you can't go back to what it was like before.

That isn't really a distinction. Prolonged inaction when action is warranted can have consequences that are just as irreversible.
