This is a pointless article. What he's saying is 'learn some self control'. I believe that if procrastinators found it easy to learn self control, they would not be procrastinating.
It's like telling an alcoholic - only drink on weekends.
I think the point of the article is obvious but I don't think the article is pointless. Too many procrastinators fool themselves into thinking they're being productive when in fact they are not reaching their full potential (PG's "type B" procrastinator). Recommending structured procrastination in the way that John Perry does is like telling a nicotine addict to switch from cigarettes to cigars. Also, the article doesn't say that it's easy to learn self control. In fact, it says just the opposite.
I've found the best way to stop my self from procrastinating is to just fullscreen my Konsole window and hide the menus, that way i just have a big black screen, and a tab bar at the bottom(which i can also hide). That only works when my work can be done in a terminal, but most of it can.
