I wonder how many and why women hate single men who use porn to fulfill their sexual needs, since they don't hurt anyone in the process?

A lot of men in that category (MGTOWs for example) say that thanks to porn they could end their "enslavement by women". Since women are the gatekeepers of sex and hence have sexual power over most men, it's seen as a relief to have an instant and cheap alternative to satisfy their sexual urge.

My question is, why this is seen with concern by certain women? From a woman's perspective, a lot of these guys wouldn't be suitable sexual partners anyways, so these "creeps" could stay out of the market and therefore not "harass" women in the first place. So the probability that a man has higher value increases due to the fact that those low value men don't even spoil the market.

Is it that women still want the attention of thirsty "sub fives" to feel better and attractive or is it rather seen as a sign that less and less men won't even try to attract women anymore by stepping their game up, hitting the gym or doing other self-improvements with the goal to be more attractive?

Or do women fear that among those men there could still be a potential partner who'd probably compare her with his favorite pornstars, hurting her self-esteem?

(I'm not asking about porn watching men, who are in a relationship.)
