All the recent evidence (https://www.npr.org/2026/03/09/nx-s1-5736553/fast-food-scree...) is that people who are best at self-regulation don't do it by surrounding themselves with tempting things and will-powering themselves not to indulge in them, they do it by changing their environment so the tempting things aren't an option. They're changing the environment via the courts and the ballot box. The people with no self-regulation are the ones complaining about the possibility of having their dopamine toys taken away.
