Woo! What a line to start on. I had a kneejerk 'heck no' response, but I buy the author's argument that the verifiability criteria and upholding the prohibition against original research can negate most of the downsides of removing notability.
I worry that it could make Wikipedia harder to search, and that pages will need to be better indexed.
What if my name is Paul Ryan, and I create a Wikipedia page for all 798 other people named Paul Ryan (http://howmanyofme.com/people/Paul_Ryan/) using whitepages.com to satisfy verifiability so that when people try and find my Wikipedia page they are greeted by a disambiguation page that would be 12 printed pages long?
In order to prevent people from using the end of notability to obfuscate, I think that Wikipedia may need to switch to a more Google-like ranked search engine.
