I'm typing this while listening to Aggroed on PAL discuss HF21 and the argument is now very stale to me.
Due to our distribution level, the mathematical changes only matter if the values of the people with the most stake act in the best interest of the platform.
Change the math however you want, but it only works if the large stakeholders actually curate. If they had been fighting abuse before we wouldn't be in this situation. If they think the Downvote pool helps them to do that and changes their behavior it would help. If their behavior continues to be all about stacking Steem faster than the other stakeholders, it will not help.
Marketing and PR would help. Attention would help.. Getting our name and project visibility would help, but Math alone fixes nothing.
I'm concerned it will turn off end users, but marketing could offset that.
In other words, Math or not, it is humans that make or break Steem there are lots of ways to attact users and if the inflationary Steem isn't used to create value it is just a devaluation of all of our holdings.
The math is not catastrophic nor is it a Silver Bullet.
At some point, the fight gets bigger than topic, discuss it but also keep it in perspective.
