I would say that in this case одних works much more like an article would and not as an adjective at all. You can't possibly say Похоже, я встречаю жадных одних женщин. I guess there's a clever world for role of одних in this sentence.
When you say that you would actually wonder why the second form is allowed, and not the first one. Of course you will say
the only greedy woman
and not
only the greedy woman
Note that одних as an article has an opposite effect of the in English. So instead of meeting the only greedy woman you meet all women who are greedy.
P. S. And the second form will be actually discouraged in written Russian.
