You are nor wrong. In another post I point exactly that out, that a bigger yield on HBD might create more demand, but that would be an investment and a good issue for us to have, we would onboard new brains and investors.
I also admit in that post that, to me, there is no right answer yet, this one just seems to be the one that has more pros and cons, because it would bring more minds and turns Hive from “only a social network” into a DeFi platform.
