As a small land owner, I have made my own goals to take a deer, and it is what lets me sleep at night. I dont own enough land to make an impact for anything, but my hunting land is in a cold area, where the stress period is winter. So I do what I can to help them out during their hard time. I offer some fall, and winter food, and some early spring food. I offer some good thick ground cover for does and fawns in the spring, and early summer. My son and I take a couple deer a year from my land, no trophys to date, but we are happy with what we take. But in my mind, the food, and cover I provide them, is a net positive for the deer, and figure because of my help, I save more then a couple deer by offering them a safe place, with some food to last them through a part of the year.
If killing a deer is your priority, then a bait pile, or high fence shouldnt bother you. If hunting is what you are there for, then in my mind, a pile of corn to draw one in, isnt hunting. As for high fences, if you have enough acres, sure you can still "hunt" the property, just as you would hunt any non fenced area, and the hunt wouldnt be much different. But it is skewed, and therefor I dont consider it a "fair hunt".
I am not saying either is bad, but it all depends on what you are after. Is your goal is to just get a deer? Then if legal, throw down a pile of corn and sit over it, you will have a good chance at being successful. If your goal is to shoot big deer, then have a high fence, and you can grow, and shoot "your" deer as you wish, and not have to worry about outside influences that may shorten the life of your deer. But if you are out there for the hunt, using corn to artificially draw deer in, isnt a fair hunt, and using a fence, to artificially keep deer to yourself until they are to your satisfaction in size, isnt a fair hunt either.
In my mind, if I see my neighbor shoot a 140" buck, I will be more proud of him, then some city slicker that paid $10,000 to shoot a fenced deer in the 190" class. But the good thing is, you be you, I will be me, I will do what makes me sleep at night, and you can do what makes you sleep at night, as long as it is legal!
