MC wants you to believe that .edus, .govs won't help.

That is not what he said nor what he intended to say. He merely offered the common sense observation that .edu and .gov links are not inherently special. What he said was that they simply tend not to fall into spammy link neighborhoods. That's it, no more no less.

Just like he wants you to believe that nofollow links are worthless

They really are worthless for ranking. Every site I have inspected that had thousands of those kinds of links ranked poorly- even the ones with PageRank five, they had virtually no traffic and failed to rank for anything meaningful.
