It sounded like you were, and I couldn’t figure out why. I’m glad you’re not and you’re open to discussion 
You seem to be treating these forums as one big, homogeneous (and schizophrenic) entity, instead of an aggregate of many individuals whose opinions are all over the place 
It’s the nature of humanity. We always want more, always want better, and, as the old adage goes, “you can please some of the people all of the time, you can please all of the people some of the time, but you can’t please all of the people all of the time.”
What you said is true: people will ask for one nerf, and as soon as it’s implemented, people will ask for another. But what you seem to overlook is that it’s not the same people. Most of the time, nerfs happen because the group of people asking for them is big enough and has been asking for them long enough and someone at Funcom thinks they have a good reason to ask for that nerf.
The only way for people on the forums to stop asking for changes would be for Funcom to drastically change their policy and state that they will not listen to any more feedback. “You get what you get. If you’re not happy with it, go play something else.” That’s pretty much the only way to squash people’s desire for change.
But I don’t think you need to worry so much about it. Like I said, it’s not like Funcom nerfs things just because a handful of people asked, without any further consideration.
My happiness with the game is not a binary thing. I can be happy with some aspects of it and unhappy with others. I can’t speak for anyone else, but I know that when I’m unhappy with a game in general, I stop playing.
That’s what happened to me between February and May. I went on a hiatus. At first I was refreshing, because I thought I would be coming back. Then even refreshing became too much of a chore, so I let all my stuff decay. Now I’m on a new playthrough in Exiled Lands and I’m having fun in general. But that doesn’t mean I can’t point out problems I see.
The key word there is “recently”. If I were to judge only from the recent flare-up of the posts on that topic, I would conclude something similar to what you said: there’s a handful of people (myself included) talking about it on different threads. Of course, if you take a closer look, you’ll notice that those threads are started by different people, not the vocal handful you’re referring to. We just jump on those topics and amplify them because we’re interested 
But like I said, it’s not just the recent flare-up. I’ve seen this pop up over and over again for at least a couple of years now. Hell, I can still recall several forum usernames who used to be passionate about a year ago. Some of them are still at it. Others have quit, either the forums or the game.
Here’s the thing, though: everyone can and would say the same about CE, but you would be hard pressed to find two individuals whose definition of what improved and what got worse are exactly the same. In the end, what matters is not a single individual – not me, not you, not JJDancer, not Hel – but everyone in aggregate.
We all care about our view of the game more than anyone else’s, of course. But in the end, it’s the aggregate that has the chance of swaying Funcom. That’s precisely why I insist on voicing my opinions here. If I don’t, I could miss the chance of influencing that aggregate.
The exact same logic? No, me neither. But I do tend to apply my core beliefs to both. For example, I wouldn’t resort to crashing the server or undermeshing or ganking someone who’s going through a loading screen, because one of my core beliefs has to do with personal integrity, and I will not compromise it just because a videogame isn’t “real”. Similarly, I will keep asking for improvements in this game as long as I play it, because I believe we all have the right and the duty to try to improve things around us.
It’s certainly feasible. It’s currently not implemented, but they could do it. But how would they justify doing it? When they ban someone, it’s because they were either cheating or harassing someone else.
In other words, the guiding principle behind their disciplinary measures is whether the person or clan being disciplined has acted with malicious intent. How would you justify limiting overbuilders? Every single example of overbuilding that I’ve seen on PVE(-C) servers has been done by players who were simply doing what the game let them do, without any malicious intent.
Other people have also insisted that overbuilding should be handled by official server rules, but I still don’t see how that would be feasible for Funcom. A private server admin has the freedom to say “our rule is that building is restricted to a reasonable size”, and when you ask them to define “unreasonable”, they have the freedom to say “I’ll know it when I see it”. Funcom has a certain leeway, but not that much. Trying to handle overbuilding through rules is just not going to work.
