Yes, that is one suggested solution for Curators if people don't want to do anything about the peg a 50/50 Curator reward evens it up.

I understand why some rewards are paid in STEEM POWER because it ensures an amount is reinvested into the long term value of the platform. It makes a lot of sense, we just need to keep in mind that all the Stakeholders need to share in the platforms success rather than letting it get out of balance.
