Linking to something from the wiki is considered irrelevant as it doesn't prove anything.

If an editor is an expert in a field and you can verify it it would be most useful to the encyclopedia to treat them as such. This is not actually a special privilege but how people normally do things.

I can gather citations and glue them into an article but someone with actual expertise knows which parts are important, what isn't and what is missing.

Wikimedia is of course free to have an encyclopedia project to entertain children with to much time on their hands but they will continue to lose good editors. You can't have both.

If you disarm the man before throwing him into the alligator pit he won't survive but it will be great for the alligators.

I don't understand your point. People who are experts in the field are treated as experts. They just don't get to unilaterally make all of the decisions.
