you very well may think that the best thing to do is simply to dissolve the Steem blockchain altogether as an entity. And indeed, that might be the best idea.

This is something I have entertained the thought of for the past few months.

One could start another chain (with slightly modified code) without the desired parties (or the ninja-mined stake that is clearly disliked) but starting over wouldn't necessarily be good for the witnesses' bottom line. I never understood why someone didn't just restart the blockchain under "more fair" conditions. It's open source and "decentralized" code.

One could spend some time thinking about the mechanics, come to the realization that you should always assume the worst when it comes to anything that can be monetized and start from scratch, restarting a chain utilizing the new found experience from the failure of this chain. But that would be harder than the prior option and could take considerable work.

One could just give up on blockchain and take some of the decentralized principles and try something else. Blockchain isn't the only decentralized way to approach any centralized problem. The only issue is there's less of a monetary incentive involved. But there are still people with "principles" left out there, right?
