My question is simple: Should we help this user (by calming him down as Andrew T. did) and concentrate on the technical side of the problem (as I did) or close these kind of questions?
I'm not sure it's possible here.
The original question is full of jargon but a few parts of it (particularly on sockets) show the OP has no understanding of what these things actually are. You put a paranoid person in any unfamiliar environment (physical or digital) and they're going to see bad things everywhere.
Sockets are a very benign and essential part of processes communicating with each other.
You could explain this and explain that TCP/IP sockets generate loopback traffic (which may explain the original question)... But I'm not sure it'll help.
The original question is not the result of a happy mind. I'll stop short of calling this a medical issue but the OP clearly needs somebody physical that they can talk to and trust. That's not a service we are qualified or equipped to provide. Just as it's probably not helpful to tell them this directly.
Ultimately, I think editing the rant down is the right thing to do but be prepared for a rollback, sprawling comment and accusations that you're one of the hackers. If that happens, flag it up and we can mute things down.
You'd be surprised how bad these stories end.
Upon reading the edit history I think StackOverflow staff could try to reach out to this person.
I know, of course, SO has no legal obligation to look after its users, but I do think that it would be worthwhile pointing towards professional help in this specific case. It is not a legal obligation, but a moral one.

Unfortunately this is not always possible (I mean point to such person that they need some sort of help). This is simply because the actual issue is the fact that for such person it is the other way around - he or she is absolutely normal (and/or just got clarity and perspective on things) and everybody else needs urgent assistance.
I witnessed (and as much as I could assisted) a total psychological breakdown of a person. In about 30 minutes time this person went from being completely sane to being completely opposite of sane. And the only thing we could do is by talking gently like to a child take that person by the hand, take to the some private and safe place and wait for an ambulance. And as it comes - this was the best decision we could do.
So why was I writing this - just to show that unfortunately without direct contact with person and close to him/her people it will be very hard to point out need of assistance. This all of course applies only to the case of person having real psychological issues. Some people may have
vivid imagination which combined with lack of deep understanding and very expressive personality may create visibility of insanity, whilst they themselves still perfectly fit into the range of
I think your actions in this case were commendable and I don't see how you could have responded better.
As someone who has unfortunately been exposed to paranoid delusions, I wouldn't be too quick to assume that this was some elaborate hoax, although I won't rule out the possibility. The rambling and ever escalating nature of the original post leads me towards belief in the delusion.
I don't believe a sane person would waste the time writing so many lines of complete rubbish just for fun. Note this rant as well: https://askubuntu.com/posts/601744/revisions as this one: I Had a Backdoor Mal Ware on W7. Will it Pass on to Ubuntu? by the same author. Sadly, it seems medication is required.
I think your response was informative. Regardless of the users many paranoias, he may just have something as simple as spyware on his win7 partition.
I think perhaps he should do a clean install of windows, and not move anything from the old install to the new one... When windows gets sick, it's like the black-plague, and any other windows system breathing on the same network is reasonably assured a similar fate.
I think my answer is probably better served as a comment, however, since it's a direct answer to the O.P.'s '?', i hope it will slide. :)
