Why does everybody hate the idea of multiplayer in TS5?

I don’t want anyone mucking around in my saves, they’re mine. Everything is my way, exactly as I like it. As a caregiver for my mom who lives in her home amongst mostly her things, and drives her car, it’s literally the only space in the entire world that’s mine all mine, decorated to my taste and organized to my liking. I intend to keep it that way.
