The more I think about this the more I like it. While I am sure some problems are created, removing the Steem reward pool and moving toward individual communities/SMTs addresses the following issues that currently exist on the blockchain depending on who you ask:

1. Bad actors with alot of Steem power who upvote themselves on garbage posts/comments, are essentially undownvotable, and anger new people who spend hours for pennies - Gone (They can form their own community and drive their own SMT into the dirt)
2. Bad actors who created 1000s of faucet accounts and slowly drain the reward pool in the background - Gone (This will somewhat be addressed in the new hardfork since we are moving away from a pure linear curve)
3. Drug Wars fight posts being rewarded Steem - Gone (We will see how many people post these in the Future coin community)
4. Actifit posts being rewarded Steem - Gone (I use actifit. It understand that some people don’t appreciate these post earning Steem. I get that)
5. Apps that drain the reward pool to stay afloat - Gone (They can come up with a sustainable business model before forming or go through a proper ICO process, etc. I don’t remember steemmonsters needing to do something like this to get started).
6. Short content posts with with high rewards, think memes - Gone (Some people only like long content. They can form their own community)
7. Current bidbots - Gone (Communities can have and police their own bidbots if they want them. The current situation has just gotten out of control)
8. A lot of other things - Gone

What else am I missing? My point being, if we move toward communities and SMTs, it is toxic to the blockchain to keep this stuff happening in the background and this is one way to wipe it clean in one go.
