On the other hand, some things (like animals and pedestrians) require some means of illumination at night.
I wonder how we ever managed to survive before electric light...
Oh, wait, humans can actually see by starlight alone.
You're not going to read a book or do rocket surgery but you can walk around outdoors without electric lights even when there's no moon. I've done plenty of hiking, etc. under a full moon.
The thing about starlight is that it's primarily reflected light from our own sun and this changes depending on which part of the lunar cycle you're in. I used to live in a small mining town 1500 KM from the nearest city (so its easy to find a place with no artificial light), you'd have times when it was pitch black and other times where you could see for a KM however the contrast was extremely washed out, so whilst you'd spot a person walking you'd have trouble seeing their face. Put simply, you'll have a lot of trouble spotting white lines on black roads.
Try doing your hiking under no moon and see how much light there is.
If this paint works as intended, it will be a godsend for anyone travelling remote roads at night, where I live there are thousands of kilometres of unlit roads.
