Well.. deer, for one.
It's much easier to spot animals crossing the road with bright headlights than without.
I still also agree headlights are too bright, by the way, but I'm just providing an example for your question

With current car that has Xenon headlights (+ LED for day), they have a much sharper cutoff at the edge, making it harder to see pedestrians and other stuff near the road.
Probably the LED/laser headlights are even worse in this aspect.
