Level 55, so not a complete newbie. Besides, attacking the person rather than discussing the idea is always bad style IMO. If you had read what I wrote, you'd note the "fake transactions" thought. Ensuring that players don't abuse the system is important, especially as people around here (and everywhere else) are known to "play the system". I don't think the experienced players would or could abuse trade if the conditions are set right. And low level players HAVE little influence on market prices - the amounts they bring to the show are just too small and their economy cannot possibly compete with a fully buffed level 6 economy. They would benefit from a more efficient market and from reliable prices (for many basic goods they are relatively stable already in my experience, that is just not transparent and visible to new players and only holds true during those times of the day when a large number of players is online). The market would not "crash" on a new feature, it would thrive because the hoarders will suddenly have an incentive to part with some of their holdings. That is bound to benefit those with fewer resources: price spreads would shrink.
BB has been good at keeping secrets and even if you were right: What difference would a few days of hoarding by high-level players make who often have starred millions or resources anyhow? Prior to Halloween people were unwilling to part with their gold coins and saved buffs/buildings for selling. Did the market change? Yes (e.g. accepting other resources for loot spots). Did the market crash? No. There will always be people wanting something and offering prices that others find attractive. That's how markets are.
With all due respect: claiming that the real world can learn economic lessons from this game rather than the other way around must be just an attempt to prove that irony never works in written communication. Instead of trying to kill the idea, how about thinking of ways to make it work?
