Pretty sure there is a sizeable demographic of people who fantasize about falling in love with an elf precisely because their relationship would be like that of a pet and owner

EDIT why did I have to go and type that out. Cannot stop thinking about 1000 year old condescending dommy mommy elf GF now. fml

Not wrong, at the same time, my wife and I were incapable of recovering from out first dog's death and we have not had a new pet since, so, as a general rule, you might be correct, but individually you can still find "elves that would have a problem with it".

under OPs logic, What's the point to let your children get attached to your parents?

yhea, love if special regardless if it's short due to death
