My take on the matter:
Why bother? You can keep all the dirty, mindless mixers who bread like rabbits largely locked away in a separate part of the Dome. Plus, humans are great cheap labor - far cheaper than robots. You can grab them up, use them until they are broken and die, then ship their ashes out as fertilizer for a remote grow-farm.
One of the big themes of CP, in my opinion, is that life is cheap. Aside from the select few, people are like grains of rice meant to be used up. Few people respect 'the value of the human soul' and humanitarian rights are just formalities. Overcrowded, urban environments are a must. And the idea of finding a humane solution over a profitable one is laughable - no matter how callous.
And there is the economy. the uber rich need a mass of disposables to stand on. People to produce and buy and sell. The Sindome world does have the tech to create a bunch of utopian, low population communities but there is a key CP element that prevents that - GREED. The powerful need people to exploit and they don't care how their greed impacts anyone else. Those utopia's are where the uber rich live and are made possible by the masses.
And yes, CP can be done in many ways. Blade Runner is CP and low population and still CP. But that is not the style of CP that Sindome has embraced. If you ask me, Sindome, at it's core, is more like Judge Dread in it's flavor. You can see this on many levels.
Additionally, I don't think that staff has had to perform many abortions. In general, most players understand that Sindome is not a place where staff will invest time in your desire to play house. Most players, when they hear this and know that they will never be permitted to birth a child, accept it and don't try and push staff into having to abort a pregnancy.
*And use of the term you or your is meant in a general sense and is not directed at a specific person. I am just too lazy to go back and adjust the language now that I realized how it sounds like I am lecturing a specific person. :-P
