If so, then why are these logically refutable scams ("Give me 1btc and I'll send you 3btc back!!!": Just think that the person would, if they can generate 4btc of value out their ass like that, simply likely keep it, whether they valued the fiat value of it or not) so common?
I understand the idea that the emotional gain from giving something to someone who has never had anything of that value may be overwhelmingly tempting or fulfilling on the "giver's" part but similarly, aren't there people more deserving of this than you, the "scam" victim? At that point, I don't even know if I would call it a scam.
If someone posed as a verified conveyancer and built a fake profile, payed legitimate businesses and entities off for positive testimonials etc. And encouraged me to hire them to re-mortgage my property for me then I would call that a scam - but someone asking for money with the vague promise that "they need it more than you" not so, similarly not with a "I will give you double the money you give me" scheme. It just feels more like something so stupid that you are entirely at fault if you fall for it.
