Oh, I'm planning the city in a way that everything that I don't want to be touched will be protected in some way.
Hybrids will be fenced, my main orchard is already fenced (there will be an unprotected orchard of every kind of fruit, but I'm making sure everything can be redone if someone start wreaking havock before I can kick them), and when it comes to external furniture, there won't be a lot of things available and what's going to be out there is already on my catalog, so it wouldn't be a permanent damage should someone steal something.
