Secondly, hunting will be harder because the deer will be able to get all they want at night so there will be no need for much daylight movement. The next action resulting from that will be people crying that there are no deer because they never see them like they used to. At best, they will be even more nocturnal than they are now.
Your other two reasons I could consider valid, however, this argument is dumb and always has been. What about the greenfields that everyone plants? Aren’t they available 24 hours of the day? Or do they close up shop at dark?
Kill a deer or two off of a greenfield and see what happens.
We had a field bordered on one side by big mixed timber and a creek, behind it was a couple hundred acres of 5 yr old pines and on the other side by a 150 acre cutover. We had a tripod on it that we called the "machine gun nest". You could honestly kill every single time you hunted it if you wanted to. There was so much spent brass under that tri-pod, you had to be careful not to roll your ankle slipping on it. And they just kept on coming in to it day after day and season after season.
