no art is necessary objectively, people will just make stuff because they like it, for the sake of itself. it can be subjectively necessary, as in one finds it valuable, but it doesn't have greater importance if people dont think it does. in general it's just people tending to their desires. I guess NSFW art tends to basic sexual desires, and it has a place in the platform. something can be said for the communities that consume the content, but at that point its not talking about the art anymore really. for NG specifically it can be rated as adult, so people can ignore it completely if they want to. so I really dont see any problem with it, it's the best way you can go about it IMO

I think you should add line breaks if you want people to read all that.
If your question can be summarized as "Why do people like NSFW?", you should try Wikipedia for answers.

Yeah, I was thinking I should maybe add gaps to divide areas so it's more readable. Thanks for pointing that out. I'll also do some of my own research. Any opinions would be nice...
