I'm not a fan of this sort of reasoning.
I agree that dating is not natural from a primitive standpoint, but that does not mean we as civilized humans cannot strive for a higher meaning within our relationships.
Even love is not entirely based on biology; instead, its concept is majorly defined spiritually and artistically.
The idea that we have to throw away all meaning that we find in life because it is not natural from a scientific or biological standpoint is absurd.
We are above non-human animals for a reason. Ideally, we should strive for meaning that transcends our physical bodies. We are minds and spirits, not mere mechanisms of biology.
This constant reductionism of beautiful things that give our life meaning needs to stop. If you are so opposed to human constructs, go live around other animals in primitive hierarchies. Civilization is another human construct, not found in any other species after all.
Every of this virtues are romantization of primitive things. If love exist or at least that so called "higher meaning" of simple thing as lust, then why you can't get it? Oh you are just a bad person with bad personaliteehee!
Do you really believe it?
That's when all of those beliefs fall apart, that bluepill ghosts, idee fixes, when you are upfront with reality which most people are not because due to luck of an ignorant they could experience something under the romanticized ideals. But when those ideals stop working then you question them.
First they will blame you for inherently being bad person or deserving the fate since they are so romanticized in ideal, they think they are something almight, something you have to succumb to and if you can't meet the requirments you are seen as worthless,
like even in the first place ideals were even real!
That's why it is needed to say that almost entire life of most people is matrix filled with ideas that doesn't even exist nowhere except in their brains.
So what we made civilizations? What benefit do you have out of it? Life has no meaning nor vocation. By experiencing life I can say that we are not different than atoms of helium. Life - counscious or unconscious are just properties of the universe just like black holes, stars, trees, whatever and we would all be better off if life completely in universe didn't exist in a first place.
We all are made to pursue our own needs therefore we are all egoists. Virtues are made to steer you for someone elses cause.
