how come the human mating dance can't be how other animals do it? in which the males have to fight another male?

here is an example of how lions do it compared to humans:

"In the animal kingdom, when a male lion comes of age he begins to make his move to acquire a female lion to breed with. If he’s unsuccessful with one group of females, he goes to another area and meets some more. Unlike us human males, a lion has to fight and sometimes kill another lion to take over the pack and territory so he can then breed with the female(s).

As a human man, you simply have to walk over and talk to women and if you’re able to get her attracted by displaying confidence, social intelligence and masculinity, then she is not only going to be interested in having sex with you, but she’ll most-likely want to be your girlfriend or wife."

So why can't it be that way? the reason why i wish it was that way at times is due to anger, rage, and frustration over having shyness, social anxiety, social-awkwardness, having below average social-skills, and i hate how me as a guy i have to overcome and improve that if i want to have a girlfriend, meanwhile women don't have to do squat for that because women don't have to be the initiators.
