You are correct that many people don't actually know any ranchers. But for the record, I'm not one of them. I've been thick with ranchers and the men and women who actually do the work for them. And that is where I get a lot of my opinions.
There is a rancher we have run into over the past several years where my bro in AZ hunts a couple of different units, AZ trust lands. The first time we talked with him I had just shot a coyote and he said "great go shoot some more". We've gotten to where we know each other and he'll ask us if we've seen certain cows with calves or if we've seen cattle in certain parts of the country where there shouldn't be any. He also lets us know where he has seen the elk or where the fresh sign is. He has told us certain water sources the elk are currently using, he'll tell us areas where there is no water at the time and save us the time of checking.
It's probably very different than ranchers with a large piece of private land and they do everything they can to keep hunters from accessing bordering public land any way possible even if it's illegal.
