Here you're talking about shallow depth of field which is desirable for portraits. But show me a camera that will have in JPG the dynamic range that you have in a smartphone by default? Show me a camera that will have as LARGE depth of field as smartphones have thanks to their small sensor.
These are all pros and cons depending on the scenario, but a phone has one advantage - it's small and you have it always with you.
Not sure what you mean by produce, it depends on lighting and photographer skill. Not like the 23mm is really a portrait lens either and f/2 isn't spectacular.
