Good analysis.
I have a reservation, though. One need for making this on hive is so that if Wikipedia ever goes down all the information would remain intact and on top of search results. How likely is it that Wikipedia goes down? Hive which is held up by those nodes and the incentives therein how about if the price of hive goes too low that it's no longer profitable and the incentive becomed not worth it?
What are the chances of this happening to hive? Maybe very low but would you say it is lower than the chances of Wikipedia going down? Definitely not, I guess.
