I really had problems with this for several days when the Steemit Inc. writers were first describing it. It seemed like they were making a strong argument that we don't actually have enough resources to make Steem work.
Then I realized that they were making an unfounded assumption that resources have to be distributed linearly by stake. They really don't; most of us with significant stake don't need all the RCs we've been assigned. Distributing RCs more generously at the low end of stake and less generously at the top would largely solve the interaction problems.
