Why Google Should Learn to Love Black Hat SEO

This could easily give some power back to the users to not get hassled by such spammy site, as well as give Google some inputs to take action against such sites.
Bring the [x] button back, Google :)
Allowing money to influence rankings (selling "mappings" is basically selling pagerank) would also potentially decrease quality; I am much, much more inclined to having websites ranked only by their quality and the quality of information in them, which is the way search should work anyways.
Oh, and a way that this could be broken: One person wants to be at the top of the results for a single, fairly common, search term. They start a bunch of "funnel" sites (hundreds, maybe), and manage to get most of them into the top ~40 pages[1] for that search term. Then, in the marketplace you've proposed, they buy up all of them from themselves, at as low a price as possible. The resulting increase in pagerank (which they're buying from themselves, so only paying google for the privilege) pushes them up to the top of the rankings for that high-value search term.

With respect to the second point - again, the answer is to keep incentives properly aligned with desired outcomes. In this case I suggested that the price for a mapping be increased if the marketer already has sold to a stable of quality sites (as determined by other aspects of the PR algo).
With respect to your third point - I agree these sorts of issues will have to be sorted out. This particular one would be easily avoided though - just place constraints on how many domains they can register as funnel sites. Yes they can try to game - but now being caught has a real risk - the loss of their legitimate income.
But there is no doubting that there will be real difficulties of the sort you mention. Nevertheless, I think the general gist is good - however the final form, black hats need to be incentivised to work with the system, not against it. And this can only be achieved by bringing them into the fold somehow.
Even if your solution were to miraculously yield better results it would still create a massive PR problem for Google, who have always purposefully kept paid and organic search rankings separately. Frankly I'd probably trust an index that directly sold SERPs rankings more than one that deliberately facilitated spammers acting as intermediaries.
Another tactic I've seen, simpler than the one described in the linked article, has simply been to link to a target site from all of the SEOer's content-scraping blogs. The core principle of what makes this all black-hat SEO is the same, though: they're building sites with the intent to manipulate search engine rankings, rather than sites which anyone would want to visit.
