RE: Steemit has problems. I have The Grand Solution.
You conflate the two parts of his idea. Stake weighting is killing the platform, not working in favor of it. It is the primary vector for oligarchical concentration of rewards.
Bots are a separate issue, and 2FA can go a long ways towards reducing bots on Steemit. Captchas can do more.
The unworkable thing is NOT taking necessary steps to reduce the financial incentives to ignore posts from authors with low stake. Rewards were intended to gravitate to good content - not deep pockets. Stake weighting VP has failed to do that, and mitigating those failures with more financial manipulation is likely to just make the problem worse.
Delink SP from VP. Make Steemit become what it was meant to be.
Destroy all bots, and make Steemit an actual SOCIAL media platform, rather than a rewards pool mining bot farm.
Edit: need to point out that's an old chart. I think the problem may actually be worse now, as that was from just prior to HF19.
It's rather naive to think bots can be stopped in open, permissionless blockchains like this one. My as well embrace it and develop a culture for good use of it.
As for identity/stake arguments, please check out my sidenote and the top comment in this recent post: https://steemit.com/flagging/@kevinwong/the-value-of-downvotes-explained
How many bots can solve captchas?
How many phones can a botnet have?
Perhaps bots can't be eliminated entirely, but using those two readily available methods, 99% of them would be gone.
@andrarchy didn't address either. Nor did you.
Your solution is predicated on the idea that anyone wants to correct the problem and not just go on milking the cash cow. I don't have a problem with people getting a return on their investment.
It's the pretense of promoting quality content that annoys me.
i.e. Don't piss down my back and tell me it's raining.
