I didn't say I think it's okay, I said the girls think it's okay.* We know this because the determining factor in whether a guy is "creepy" or "hot" when coming on to a girl is not the manner of the approach but the attractiveness/social status of the man.
Fat nerd: "Oh hello m'lady, I would very much like to buy you dinner and get to know you better, if that would be all right with you." Polite! Nice! Creepy. Reported to HR.
6'2" Tom Brady looking motherfucker with money and a nice car: "I'm gonna buy you some furniture and then fuck your brains out on it." Bizarre! Awful! Hot. Gets laid. "Teehee he's so aggressive I just love it!"
Now morally I don't agree with any of this casual sex hook-up crap and I think it's ruining civilization turning the women into trash objects and the men into either vapid playboys or bitter loners and now 70% of men 20-35 are unmarried. Kind of disastrous for the next generation. But this is how women behave. It's called "hypergamy." Eggs are expensive, sperm is cheap, don't waste expensive eggs on low-quality sperm.
When I was younger I was selectively famous in a niche artistic circle. People knew who I was. I'd go to a convention and girls way out of my league would want to climb me like a tree. Just because I had a little bit more social status. Go back home and go to a club where I was just another guy and not a second look. That's just how humans are wired. This is why 80% of the women on Tinder are only fucking 20% of the guys.
* I went and read your article and it says basically the same thing I did: whether something is creepy or hot is determined by the boundary set by the woman. However women set very different boundaries for rich hot guys than for fat nerds. The moral of the story is "don't be a fat nerd."
