No ambition, like Fred555 said, or they want HBO and stuff like that. I had a guy stop here one time asking me about my 9' dish when I was out working in my yard, he'd said he'd seen it moving one day when he was driving down the highway behind my house. I talked with him for quite a while explaining about it and he understood everything good, he was all hyped up to go find a dish until I told him you couldn't get HBO, Showtime, etc. Tried to tell him that there was a lot up there worth watching, but his interest level was pretty much zero then.
I have people ask me quite often about setting up a dish, or OTA antenna, but when it seems like they have to do a little thinking or work, their interest usually plummets.
Like FatAir said, cameras are a good thing to deter scrappers and other unwanted intruders. I just updated mine to newer ones, Zosi ZG2317A's, day/night [color during the day, B/W at night] they were only $21 on Amazon and work great so far, been about a month. I did get one bad right out of the box out of the four I bought though, but it was replaced with no issue.
