having kids is a personal choice, but your argument as to why is stupid because you ignore all of the good aspects of having kids and all the bad aspects of having a partner
firstly, your entire argument revolves around money. having a partner is good because 2 incomes means more money, having kids is bad because it means less money. But if you ask any loving parent, watching someone that they grew from themselves learn to read, or ride a bike, or pass school, or get married themselves is worth far more to them than anything of monetary value. Im not saying that you need to reconsider your stance, but stop applying your worldview of "money is the most important thing" to every other person
also the concept of being "tricked by your biology" is retarded asf. You are not separate from your biology, you ARE your biology. You cannot be tricked by something that is part of your being. The need to eat, drink, shit, sleep, love, cry is what makes you human. Trying to disconnect yourself from your biology doesnt make you some enlightened individual, it just sounds like a sad way to live
