After hardfork 21

One thing many people overlooked is we shouldn't have had over a 5% inflation. And with hf22 we have no need for steem mining via content.

Since steemit can have its own smt. This would turn steem into a utility token. We could still have sbd be printed via witnesses and node ops if it's really needed.

The mining of steem should be switched over to node ops, and witnesses. This would strengthen our infrastructure massively and lower our dependence on steemit or any centralized org.
