As I said in the article the limiting of posts doesn't actually work because it has problems but it was included as a thinking area. It doesn't work for a number of reasons including things like zappl. It keeps coming up though because people confuse Steemit with Steem. They have comflicting desires. They want steem to the moon as long as it is on their terms.
What is of interest to think about here though is actually the splitting if the reward pool. But, no one so far has mentioned it. Most likely because they focus on the parts that affect them now.
