Do you think that it's completely implausible that someone would want to experience those emotions too?
I'm not claiming you'll have much success giving only those, but the wider the range of emotions you can incite, the better.
The claim that most would want this is more extreme and more difficult to find evidence for. I have no evidence beyond my own experience.
Even if it genuinely made the object of your love happier?
The essence of all persuasion, manipulation, whatever you call it, is giving others what they want; sometimes knowing what they want better than they themselves.
If they are as cold and calculatingly manipulative as you imply, most people who do PUA would almost definitely have no problem being kind, committing and caring towards women if that worked, i.e. made women happy to be with you.
