Great discussion, thanks for your reply!
Yes, I think we're also discussing short-term and long-term effects here. Short-term the dilution effect of SBD isn't as strong as e.g. the "soak" effect of new people coming and wanting SBD and Steem. Longer-term this will look differently, as you described.
However, I may adopt some of your payout-strategies once the amount I'm making becomes meaningful :-)
