It would stop increasing (about 0% per year after inflation rather than 3.5% or higher currently, all else being equal; over numerous years even this is a BIG difference). Okay maybe that's still not ideal, but it is better.
We could use a solution to the rich-getting-richer problem that is sort of baked into proof of stake, but unfortunately we don't have one. Sticking with the existing system is not only not a solution, it is making matters worse.
Meanwhile we stop needing massive inflow of new capital (which mostly isn't there) just to maintain the price and value of Steem from draining further down the toilet. Like I said earlier, it buys time to find solutions.
RE: How viable is Steem as a currency as the Steem network must constantly create tokens to reward bloggers and enable votes (causing lots of inflation)?
