With the changes likely coming to the inflation rate, how would this kind of adoption affect the daily rewards pool? How would it impact scalability? 

Currently, the rewards are enticing and payouts can be fairly lucrative for good writers/bloggers - with only a few thousand active users.  But what would happen to payouts if Steemit and the various other platforms were to reach one million users over the next several months?  How would the rewards pool look if there were 100,000 active users per week instead of less than 10,000 - price being the same as it is today to keep it simple? (I realize that prices would likely rise if there was rapid, large-scale adoption.) 

My understanding was that one of the reasons for the higher inflation was that it would allow for better scalability. Was that a misunderstanding? Don't get me wrong - I think the proposed changes are a net positive for the currency, I just wanted to know how this can affect the pool.  I would imagine that this would significantly reduce the average possible payout over time as the user base increases, unless there is a near equal rise in Steem price. 

Any clarification is appreciated.
