@milo23,
1)because except for the Amish, people no longer tend to travel by horse and buggy.
2)because both actors and producers are insanely greedy and desire a lifestyle much akin to obscenity. Living in multilevel mansions with dozens of bedrooms, baths and oddrooms on several acres of land, all of which much be maintained by a staff which needs to be properly paid. Not too mention their several automobiles....
3)because of regular increases in salaries of those employed by the electric, gas, phone and cable companies, along with the local area's water supply and safety, which must be overseen and maintained for your safety.
Best for you to find a comfortable cave in the mountainside and move in there. No fancy electronics or running water ( unless you have a piping system set up to a nearby spring) but it'll keep the rain off of you and come winter you'll have a nice bear to keep you warm.
