If you assign a dollar amount for the use of PUA methods you will find that you pay much more than you get in return. It's like investing $1000 to get $50 in return. Now I will admit that for some that $50 is very important, like if you're a virgin and/or sexually/socially inexperienced. Then that $50 return is worth all the effort. But over the long term the use of PUA methods is definitely a losing proposition. Once the novelty fades it quickly becomes a low yield exercise in terms of results attained, and it has the compound effect of hurting your self image since you are trying to change who you are to adapt to what women are attracted to. I personally would rather pay for sex than ever use PUA methods again. It's a much more efficient use of my time. The closest thing I would ever get to using PUA methods again is to do mass approaches, but with my personality on display, not PUA material. And I would do this in order to get a regular girlfriend. In this part of the world where I am it's simply not worth it to be a player who hooks up with lots of women; the reason being that cold approaching here is very low yield. Therefore, it only makes sense to do it to get a steady girlfriend.
But if you want sex with different hot women on a regular basis then prostitution is the best way to go about it. It will save you all the grief, anger and emotional frustration that comes with using game - which by the way is a much higher price to pay than paying a prostitute, in my opinion. And it's even possible that a prostitute will cost less money anyway. For example, if you habitually go to clubs and the cost per club night is (say) $40-50, then you might end up paying hundreds of dollars before you finally hook up with someone (not to mention the many hours of approach effort that it took). For this amount of money you could get sex with a guaranteed hot woman, but with none of the effort.
So with all this in mind, these are the reasons I've come up with in favor of prostitution:
• You are only spending money, as opposed to money plus time plus effort, or time plus effort at the very least.
• It crushes the evolutionary argument that very attractive women always seek men with superior genes (mostly espoused by PUAs). So if you got money you can buy sex with a very attractive woman regardless of how much "reproductive value" you have as a man. This is a great thing and perhaps more fascinating than the use of "game" to get a higher quality woman since game is just an attempt to enhance attractiveness. But money is simply a shortcut to get the same result without any of the effort to boost attractiveness.
• Prostitutes compete with each other for your business/company, which helps raise the quality level of their service. This is unlike typical western females in the dating game which feel no need to compete for a man, so like a tight trade union they collectively lower the quality of what they give to the man while expecting much in return. But for prostitutes, giving little means the man just "shops" elsewhere next time. This is a switch from the dating/courtship/pro-female/male-supplication model to an economic model for which payment for quality of service is the only criterion for the pairing between a man and woman.
• In the economic model where the man pays directly for sex, the seller (the woman) typically respects the buyer (the man) much more than women in the dating scene do. The western dating scene is also based on a buyer-seller model, but one which is cleverly disguised with fake courtship rituals and relationship quid pro quo, with the added insult that the sellers (the women) typically disrespect the buyers (the men). It's like walking into a store, and instead of being greeted by the merchant you are ignored, and even scorned just for being there. You are starting from a negative position which you must climb out of somehow. In other words, you have to prove yourself worthy before even ATTEMPTING to buy.
• Paying money instead of using game means you don't have to change who you are. If you want to get laid, you just pay money, and your personality stays basically intact. So given a choice between the two, a truly alpha guy is more likely to just pay for sex than change parts of his personality in order to get women to have sex with him. Now some guys will say that going to prostitutes sucks because the woman doesn't actually like them, and is just doing it for money. To me, as long as I just want sex, it wouldn't matter to me anymore than if my mechanic likes me as a person. As long as he can properly service my car, that's all I really want. I'm not paying him to like me. I'm paying him to service my car, the same way I would pay a woman to satisfy me sexually. However, I would want her to respect me. That is important, the same way it's important that my mechanic respects my wishes with respect to my car.
