In your thought experiment, cost effectiveness is the only consideration mentioned. That's why the answer I have already given still stands.
It's your thought experiment. I'm not going to refine it and argue against myself.
Well it wasn't the only factor mentioned:
Really. Ok, try this for an example.
Let's say, hypothetically, that some research is done and it's found that abolishing all rape crisis and counselling services is the most cost effective option. Societal cohesion doesn't appear to be adversely impacted, overall productivity stays the same, as far as anyone can tell. Turns out that most people manage to deal with it, and for the extra cases that are more problematic, just giving them a few pills to keep them in robot mode works out cheaper than paying for counselling services, etc.
Obviously, in this case the most utilitarian option would be to abolish those services. Should we do this or not?
Bear in mind that you are talking to someone who can easily remember when none of these services existed, and society stayed together just fine, with good productivity.
So, to be precise, the factors considered were:
1/ Cost effectiveness
2/ Societal cohesion
3/ Overall productivity
4/ Resiliency of many victims
5/ Exceptionally difficult cases, and how to treat them
