It's not the house interiors that cause the problem, its the housing wards. They are also individual instances for every. single. ward. Someone a while back did the math that translated into thousands of zones across all the servers that are always up and running. I will have to look for that post again, but as they basically said, the wards on their own don't seem like much but when you add them all up, every world has far more housing wards than all the rest of the regular zones in the game, put together.
