You haven't chosen anything. That's the point - the illusion of choice and agency.

If you can't stop cold at any time if/when you decide to, you don't have the agency to make a free choice.

I can though, that's the whole point. I chose to quit Facebook and Reddit. I chose to stop drinking alcohol. I chose to keep smoking weed. Some choices are better than others, from certain perspectives, that doesn't make them any less my choices!
