Logistic is effectively the same model as "exponential until pressure from a ceiling is applied". Look at formula for its derivative, it is the exponential multiplied by a factor that goes to zero as the ceiling is approached.

"Until pressure from a ceiling is applied" is the difference between stabilizing at 9 billion people (a bit more crowded than right now), and growing to so many billions or trillions that the grandparent poster's "no more toilets" prediction would be realistic.
