Deletion of Economies of agglomeration

Comment: Written like essay is not valid reason for deletion. Also the vague nomination doesn't statr true state of the article. You claimed it's "unsourced" but that's utterly not true and anybody can verify this. It has 10 valid sources including academic books and print sources. You said you couldn't find '''any''' source; although strange, I can |believe you, but with pointing that others have found sources and the article has sources, decent sources for that matter.  Your claim of unclear focus, this may be slightly true especially if you say "poorly organized" and even then, it is also not valid reason for deletion. It just needs copyedit when willing volunteer come around it. https://en.wikipedia.org/wiki/Special:Diff/819693316 You earlier tagged it for PROD and it was speedily challenged. If you can't fix it leave it for others to fix and that have no deadline
