It is kind of disingenuous to say:

Perhaps one of the most underrated benefits of the RC system is that for the first time in history it enables truly free account creation by any Stake holder.

Since the only stakeholders that can create an account currently need to have 4252SP per: Creation of new Steem accounts without waiting and paying anything (with new Resource Credits system)

With current cost of claiming an account, you would need to have at least ~4252 SP and 100% of RC to be able to claim 1 account.
