If you think the problem with light at night is hogwash you need to read it again. Bright light, especially blue light makes your body react like it's daytime. Do you really think people have forgotten about the sun? You only hurt your own understanding by being so quick to dismiss others.
You're preaching to the choir. I'm well aware of the melatonin-reducing effects of blue light, but the streetlights are a drop in the bucket compared to phones, televisions, and tablets. The one time I actually want to have my melatonin levels suppressed is when it's late and I'm operating heavy machinery.
We could mandate that people driving at night must drink at least one cup of coffee per half hour, and it would make them be more awake in the short term, but it would be a terrible idea for similar reasons.
