I grew up in Arkansas where baiting is just how deer hunting was done when I grew up. So I don't really have a problem with it myself, but I do think if you haven't hunted in heavily baited deer areas that you'll be surprised how quickly the deer adapt to it. It's not just go throw a bag of corn on the ground and collect your deer. I see 100x more daylight activity in TN around my throw and grow rye food plots than I see in Arkansas around a bait pile, deer feeder, or otherwise. And it's easier to get in and out of the plots without spooking deer than it is to get on and off a bait pile since those deer will show up at dark and might not leave for hours. Most years I'm more likely to kill my buck in Arkansas by not baiting, and relying on my neighbors to push the deer to live on my land during the daylight, and only go to their piles at dark.
Average hunter is more likely to destroy their deer hunting with corn piles than they are kill big bucks over them in my experience. I think there are a lot of valid concerns with legalizing baiting, but the complaints about it not being deer hunting, my neighbor is going to ruin my farm by killing all my big bucks with 200 pounds of corn, or anything like that is probably not what you should be worried about. Believe it or not there is strategy with bait piles as well.
Like Ski said, the people you need to be worried about are the people with money to blow. They can be so much more efficient that they can go lease 10 or 15 30-40 acre blocks, dump a couple thousand pounds of bait out, put a camera on it, and they might only hunt 1 deer on one lease for the entire year. Where they wouldn't be able to manage habitat and food plots on 15 properties. It becomes an access issue, and arms race pretty quickly.
I know a lot of every day average joe hunters in Arkansas that put out 5 or 6 tons of carrots, potato and corn out. These are not wealthy people. So you might imagine if you get next to a neighbor with money, can manage their property, and provide infinite food, cover, and low pressure any mistake you make will just make his property better and yours worse. It will be very difficult to compete with that, but it was already going to be difficult to compete with them anyway so it might not be that different. It's just hard to pull deer away from a mountain of food without another mountain of food. Your 50 pounds of corn will feed the coons, birds, and other critters and the deer will ignore it unless you also spend big to compete.
