The alternate view is that Wikipedia, and crowdsourced information resources in general, are an aberration brought about by the confluence of anonymity, interactive technology, and narcissism. Take any one of those things away and you have a failed project, and take two of the three things away and the project actually does go away completely, and fairly quickly at that.
I don't think anonymity's a major issue. It's a historical accident (that could have gone other ways in a parallel world) that IP addresses aren't listed just like phone numbers. If culturally all users of the parallel internet took for granted they were identifiable, they'd still create blogs and collaborative crowd projects. The expectation of anonymity does encourage problems, though. If that's what you mean. But if that expectation hadn't been in the net's original setup, we would still probably end up with blogs, forums, linux, and other crowd endeavors, even if users might act more responsibly.
I'm also not so convinced about narcissism. "People do it for recognition and to look/feel good" applies as much to a job, a research program, charitable work, or playing music, as to online editing. At some level most endeavors have some element of self-image bonus.
Unfortunately, the thing that's probably most valuable to society in general, namely anonymity, is also the thing that's easiest to misuse, and also easiest to take away if you're a government responding to demands for privacy, even-handed treatment for all publishers, social accountability/responsibility, etc. etc.
No argument on this.
