I'm pretty confident only a small fraction of people edit anyway and those who would only need a few encounters to start becoming editors.

This is based off the fact that I frequently see:

- "why does X not have a Wikipedia article?"

- "this Wikipedia article is so poorly written"

And very rarely actually see someone edit it. On occasion thousands of people have agreed and hundreds of people have written comments agreeing and only two people edited.

So maybe it does some damage at the margin but overall probably doesn't hurt that much.
