Because not everyone is as careful or adept as you are. Even if you turn off data roaming, you will still get incoming phone calls on your home SIM. Having said that, my experience is with Android where you can turn a SIM off entirely. My overriding point is removing the home SIM makes it impossible to accidentally roam, so why not remove it?
