Illinois is a bigger state with a lot of variation in landownership. There are parts of the state, especially in the northern part of the state where many farms are thousands of acres, but it is different in the southern half of the state. In the area where i am from, tracts generally range from my very modest 19 acres of woods to 200-300 acres of combined fields, pasture, and woods.

People are well within their right to post their land to hunting or lease it to small groups that post it and use it to farm trophy bucks. But, the flip side to that is that you end up with very low hunting pressure and very large numbers of deer in generally, especially does. It gets even worse when the big buck mindset comes to dominate. People hitting deer with cars and havng their fields and gardens torn up by too many deer is pretty common.
The same farmer that leases his land for 5K may end up with 10K in crop damage because those leasing the land only shoot a few big books.
I prefer the old days when the numbers were low and getting any deer was a challenge that was appreciated. Nowdays you get people who literally go into depression if they don't tag a 10 pointer or bigger every year. What a change in 20 years.
