Lasers+Adaptive optics compensate for the blurriness induced by the atmosphere, but not for the light pollution. The whole sky glows because of it, and items significantly fainter than the glow baseline are lost, even in long exposures.

I visited La Palma in the Canary Islands just before the lockdown in Spain. La Palma has a huge observatory, and I learned that the island is a starlight reserve. They take active measures to diminish the effects of light pollution, such as using special street lights, limiting flights at night, etc.

If you ever get a chance to visit, La Palma is am amazing place.

Tucson, AZ is another place that has rules to guard against light pollution. This is to keep skies dark for the nearby observatories.
