Also, new people could be created, what’s the difference between being born in the “real world” and the simulated one?
If the simulation is sufficiently accurate to generate qualia, they’re real people. If it’s only sufficiently accurate to convince me that they’re real, they’re not. I agree that you can make a simulation that actually has people in it, but the point is that you can also make a simulation that makes me think my desires are fulfilled without actually fulfilling them. I have no desire to be so fooled.
