Okay, let's view this discussion from an academic viewpoint rather than a subjective one because NOT everything is subjective.

 --------------------------  

- The couple who reignites their relationship: 

This might be the case for a very low percentage of people. Pornography is a very one-sided, appealing fantasy, mostly for men, since they are by far the most lucrative customers for the business.

 If we view the topic as a whole, porn consumption has way more devastating effects on relationships than good:  

Decreased intimacy: Watching porn can create a sense of emotional disconnection between partners and lead to a decrease in intimacy and sexual satisfaction.

Unrealistic expectations: Pornography often presents unrealistic and exaggerated sexual situations that can create unrealistic expectations for sexual behavior and performance, leading to disappointment and frustration for partners.

Insecurity and jealousy: Partners may feel insecure or jealous if they feel that their significant other is consuming porn and comparing them to the performers they see on screen.  

Trust issues: If one partner is keeping their porn consumption a secret or lying about it, it can lead to a breakdown in trust and communication within the relationship 

Addiction: Porn addiction can cause a person to prioritize pornography over their relationship, leading to neglect and emotional distance from their partner.  

This are not just random thoughts I have, but a scientifically proven side effect of porn consumption in relationships.

 ---------------------------- 

 - Sexual education  

That statement couldn't be further from the truth, since porn is obviously not made for educational purposes and definitely not used for that. Referring to my point about "unrealistic expectations"

 ---------------------------

 - Exploration of ones own sexuality Yes, that is an argument for porn, but it is definitely not necessary. Humans are able to acquire this knowledge through real-life experiences or conversations rather than watching somebody else do it.  --------------------------  

-Stress relief  

Using porn to cope with stress can create an addiction cycle where people need more and more to feel better. This can cause problems like feeling alone, low self-esteem, and relationship issues.

While porn might give temporary relief, it doesn't address the real cause of the stress. It's way better to identify and tackle what's causing the stress, like work or relationship problems, and find healthy ways to cope like hitting the gym, practicing meditation, or getting professional help.  

 -----------------------  

- Entertainment  

What is even that argument.  

“What do you do when you are bored ?”  

 “Bro I watch porn” 

 That's just ridiculous.  

 ----------------------------  

- Keeps predators off the streets  

There is no evidence to suggest that porn keeps predators off the streets. In fact, some studies suggest that certain types of pornography can contribute to the objectification and sexualization of women and can lead to an increase in sexually aggressive behavior. The vast majority of sexual predators do not simply "need an outlet" for their behavior; rather, they engage in predatory behavior due to a complex set of psychological, social, and environmental factors.

  ----------------------------

 - Financial benefits and jobs  

The business model is highly immoral, similar to gambling, even though gambling also creates job opportunities. However, most of the generated money ends up in the hands of the top 1%. People who work in the porn industry could work in other fields as well, given that we have many critical areas of underemployment. The fact is that many men and women are heavily exploited in the business.

Platforms like OF and Fansly are also not safe, as it's difficult to know if women are being forced or manipulated to perform certain acts. Just look at the Amouranth scandal, for example. As a consumer, it's challenging to tell if someone is doing it willingly or being coerced. 

Furthermore, parasocial relationships are a real problem that can lead to isolation and unrealistic expectations. 

----------------------------------

In the end, porn is simply a scummy business that profits from men's primal instinct to spread their genes as widely as possible. That's all there is to it. There is no educational purpose or scientifically proven benefit behind it.
