why would I not simply CURATE his posts from here on out, instead of real content creation?

and why shouldn't you? If you curate, it's with your stake to do with as you please.

The ratio of curators (content consumers) to content creators on Steem is very abnormal because content creators are disproportionately rewarded. But that results in a low-price equilibrium where nobody earns as much as they should. Giving curators back more of their own stake ('Come earn money curating quality content') for being effective curators will improve the amount of organic curation taking place.

I oppose the EIP because there are serious issues with downvote pools and the new rewards curve, but 50/50 is the best part of the proposal. If we could have just 50/50 and SPS I would be a strong advocate for the HF21.... because it would almost certainly result in a rising STEEM price (even relative to bitcoin).

So, rather than make posts, I stop being a content creator and only curate?
What happens if we multiply that by thousands of creators and authors?

Each user will make their own judgment call about whether to continue as a content creator. It won't be everyone, and if enough organic curation remains then the remaining content creators may do better than they were before.

My concerns are more about the impact of CLRC (convergent linear rewards curve) and downvote pools. Those I think will be devastating impact and make change to 50/50 totally irrelevant in the broad scheme of things.

the 2 or so free downvotes will have ZERO effect.
What user with a rep of 45 or 50 is going to downvote a user with 100,000 SP and a rep of 70?

Exactly right. Economic costs are gone, social costs remain... But social costs are zero for accounts with no social standing to lose.

The upcoming downvote was will likely be devastating and their impact will have a massive impact.

I'm told by dependable sources that at least 10 million SP will be brought into downvote action. It's not about the tiny accounts, but the mighty and rich.
