Paris has rules against shop lights from 1-5am to deal with light pollution and energy waste. So of course, someone had to try to go around the rules.

Lighting in cities is generally a good thing.
Circadian rhythm disruption. 90% of people in the civilized world live in cities and most don't use pitch-black window blinds or curtains.
It is bad design if people are unable to have darkness where they
sleep. Good lighting design fixes that.
A city without lights would be terrible.
Cities in the West are moving away from wasted lighting, thankfully. In fact, in Toronto, it's darker in the core of the city (most of it) than the suburbs.
And yet, cities everywhere are using more and more lighting for pure
decoration.
