I think I understand the point you're trying to make. My opinion on that is the following:

RCs are a reason for people to buy STEEM, which is good! Author inflation isn't necessary, nor desirable for people to gain enough resource credits. Inflation will always result in selling pressure, but we need the opposite - buying pressure. Now, if you want people to gain more RCs over time, then increasing the inflation for stakeholders is the way to go, because it incentivizes people to buy Steem and hold Steem.
