What are your interests then? Within and without the scope of a relationship? What is your interest in dating? Do you feel compelled to date because it sounds like something everyone should do, and not doing so marks you as abnormal or dysfunctional? If you don’t feel particularly compelled to date or enter relationship, then no, it isn’t worth it.
Similarly, if you suspect you have interests that would clash with having to seriously date or being in a relationship, then maybe the best compromise is not to get in a relationship. it may also be possible to enter a relationship more suited to your needs, one that can preserve your other interests, time and freedoms, if your drive to date and be in a relationship is strong enough to be unavoidable and compete with your other drives.
Besides, serious “classical” dating (in fact, what do you mean by dating? What kind of activities and investments were you thinking about?) is neither a necessary nor a sufficient condition for a satisfying relationship.
But it’s still a compromise. Is it part of humanity’s utility function to value another species’ utility function to such an extent that they would accept the tradeoff of changing humanity’s utility function to preserve as much of the other species’ utility function?
I don’t recall any mention of humanity being total utilitarians in the story. Neither did the compromise made by the superhappies strike me as being better for all parties than their original values were, for each of them.
The only reason the compromise was supposed to be beneficial is because the three species made contact and couldn’t easily coexist together from that point on. Also, because the superhappies were the stronger force and could therefore easily enforce their own solution. Cutting off the link removes those assumptions, and allows each species to preserve its utility function, which I assume they have a preference for, at least humans and baby-eaters.
