This assumes a single machine scanning, not a botnet of 
1000 or even 
the 1.5m the dutch gov't collected 2 yrs ago.
Again, a sane discussion is in order. Scanning isn't AS 
EASY, but it 
certainly is still feasible,
With 1.5 million hosts it will only take 3500 years... for a 
_single_ /64!

I'm not sure that's what I would call feasible.

I would call that not understanding today's security world. "Scanning"
is not the primary mode of looking for vulnerabilities today. There are
several more effective "come here and get infected" and "click on this
attachment and get infected" techniques. 

What scanning that does go on today usually not the "lets scan the
Internet." No money in it. You target your scans to the address ranges
of the sites you are trying to mine (i.e. build BOTNETs) or go after.
