On a separate note, I got a kick out of the phrase, "the real world of philosophy." I know what he's getting at, but it still sounds oxymoronic.
What he misses is the real problem: in academia there is more of a value placed on who you are, than on what you do. People place more emphasis on institutional afiliation than they should. Rather than judge people on the merits of their work, too much weight is given to where you trained, and who trained you.
Nothing the author says actually addresses the core issue. In fact it seems like his issue is not being the important person. It should, however, be with how work is evaluated. Fixing that would solve the core problem.
