The name for what you want to do is not a community wiki. A community wiki is easier to edit by low reputation users. You actually want to edit the question now and then lock it so that it doesn't attract future edits or supportive answers. The wiki format struggles with controversy. On Wikipedia, they tend to lock topics like this so that they can't be edited.
This would be a horrible question on which to hang "What is the Fed?" duplicates. I'd just ask a new question and get a new answer or answers. The current answer is too closely associated with the current question to make a good description of the Fed. Corone would have to chop out half the answer.
Note that this question is really a gold standard question. There's a group that wants to bring back the gold standard with full reserve banking. They blame the Fed for a variety of ills including the purported impossibility of paying off the government debt. Ron Paul is a proponent of this view and it has a sizable following in absolute terms although small as a percentage of the population. Closing questions like this as duplicates of a "What is the Fed?" question is just asking for trouble. If you want to keep them off the site, just close and delete them.
There are some questions that could be closed as duplicates of this one. I just wouldn't describe them as "What is the Fed?" It's more, "Could we replace the Fed with a gold standard?"
If you want, I could edit the current question such that it displays a better understanding of what proponents claim.

seems to run contrary to the idea of flagging duplicates $\endgroup$
