I intentionally mentioned behaviour changes first in my comment, we can't fully separate rules and lockdowns from voluntary behavioural changes. In the end all that matters is the changed behaviour, not whether it was enforced or not.

Full lockdowns are also not the best way to handle increasing numbers now, they were necessary earlier this year because we didn't know much about the virus and which situations are the most dangerous. With the knowledge we have today we can use more specific interventions to contain the virus.
