There's a lot to be critical of in SimCity (small city sizes, questionable routing, the online disaster, flat out bugs) but 'fake' Sims is not really one of them.
As long as the extra "population" is still derived from all the agents you see running around, all it means is that a single agent represents a number of people. This is still a radically different approach to the simulation than any previous SimCity which are essentially just systems of differential equations laid out on a map.
Now the mob mentality when the Sims all rush towards the same single house only to turn around when the first of the mob fills it? That could use some work.
