Well from an investment point of view, you're mostly looking for some kind of dividend and hopefully a price increase. At the current time I think it's fair to say that the bidbots provide this kind of dividend to investors, but are definitely putting downward pressure on the price long term.
Again, I do like the passive approach proposed here, but I strongly believe active investors should be getting more out of the platform than passive ones. How to make this a reality is a different matter and likely not easy to solve.
If we look at the whales on Steem for example, we have a lot of them who are very talented developers / community managers / etc. etc., but a lot have stopped doing any of that on Steem as the work vs reward just makes it way more tempting to use bid bots. Even though long term if bid bots remain around, they could very well be the end of growth for Steem.
Making it passive, as proposed here, won't get those people to do more again for Steem in my opinion, where they did have the motivation to do it before bid bots came along. But it would at least likely eliminate most bid bots, which is something I am really looking forward to.
I do think that the proposed solution here is a lot better compared to what we have now with the bid bots, but at the same time I think more incentives for active participation would not be a bad thing either.
