If you want to destroy an economy, all you really need to do is introduce a lot of chaos and uncertainty. These these changes bring a lot of both. Along with those, you have the perceived unfairness of the 50/50 change. Doing nothing is one thing, but doing everything at once is worse. People WANT incrementalism, despite what the devs say what needs to happen with respect with the exchanges. Everyone is fretting about "muh investors", but the product here on Steem is the creators, and if you drive them away the best of intentions won't matter.
