I'm not sure I would want to be married to someone I could
only stand because I took drugs.
That's the naturalist fallacy: implicitly assuming that the 'natural state of affairs' is by definition better than an 'artificially' created situation. Taking a pill is no different from living in a house. Both are unnatural. Both can make life a lot easier.
It's also the fallacy of the split middle: it's not either 'you love someone' or 'you can't stand them'. If you're in a loving relationship that has gone downhill somewhat and a few medicated sessions can renew the bonds, is that really any different from going on a second romantic honeymoon, where you also create artificial circumstances to strengthen the bond? Physical forces or cultural forces: they are equally real and do equal work.
