Not in all situations, doing nothing is doing nothing. Take the famous trolley problem. By doing nothing you pick 5 people to die, if you do something you pick 1 person to die. One of those will come true, either inaction or action will determine which. But that also means your inaction is an action of yours to force an outcome. This doesn't necessarily mean it's the outcome you want or the outcome that is preferred. Inaction can be the worst type of action to take in some scenarios, but it is the action of non-intervention that creates an outcome regardless. Inaction doesn't mean you consent to the outcome either.
