I don't think your example of dating is a very good one. You're changing the functional nature of the date by having someone else go on it. That's like saying you can't outsource hair-cutting to a barber because it would be equivalent of telling your friend to go cut his hair for you. Clearly you need to be participatory in some degree for the activity to retain it's functionality, but that doesn't mean you can't outsource the hard parts to someone else and have everyone be better off. (Maybe it's unrealistic, but personally I think we do need a bit more outsourcing in dating. We don't need to have everyone muddle through it by themselves, we can have skilled people help educate and guide us in how to find healthy meaningful relationships.)

And honestly, I simply can't help disagreeing with the idea that everyone should raise children themselves, just because we will "look back on it with fondness". That seems to me to be the equivalent of saying (pardon the awful analogy) that people should kidnap women off the street and rape them because they find the experience "pleasurable". The way I see it is that by raising a child you are forcing your will upon them, they did not ask or consent to it and have no say in how it is done. And yet, child raising must be done somehow, and therefore you have a serious responsibility to try to ensure that it is done as well as it possibly can. You have no right to force poor parenting onto a child simply because you had a "nice experience".

I realize my views on this may be a bit unusual, but I think it's worth considering.
