Look at me I can edit what other people say and look hip doing it!
Translation: we're less of a community of nerfers and more
of a bunch of selfish people trying to extort money and make sadly marginal profits Intelligent entrepreneurs . Aren't we awesome
I've said this a lot on IRC, but since you don't seem to visit, I'll say it again: Anyone who tries to make large amounts of money in Nerf trading is a douche.
Note that this does not mean Nerf selling; I don't care if you make something cosmetically appealing, make a youtube video of it, and then market it on ebay for $500. Your buyer most likely is either an airsoft fanboy, has an odd system of utility, or is stupid.
Nerf trading, on the other hand, is supposed to be nerfers helping each other out. However, like any system of trading in a specific community, it'll turn into a metamarket (actually, it's a submarket, but this type of market occurs most in the metagames of MMORPGs, so I refer to it as a metamarket). For someone to try to make money from this then, would be abusing the metamarket, and makes you a douche. It is on the same douchiness level as the higher uppers in our awesome capitalist system who thing they are entitled
to $bignum salaries because they graduated from $bumpersticker school.
A metamarket in principle is stupid. They revolve around a targeted product in a very small buyer pool, with no real value outside that buyer pool. Classic metamarkets would be the people who sell WoW or Runescape items/gold for real money. Next, a metamarket contains no real money. The easiest way to look at this is the modding services category. Someone offered me $40 to buy the BBB I debuted at Chano 2 (and then posted about) and then used again at SPANO. Great deal right? Not really. Total time spent on the gun, including planning and buying materials, comes out to around 9 hours, and even at minimum wage, that's at least $60 worth of time. Exception of course, lies in the xbow market.
But while the xbow market may have profits, the very nature of it makes anyone who abuses it a douche. The given value of the item is much higher than it's real value; this makes the system economically stupid. The existence of the metamarket is dependent on the community; anyone abusing the metamarket is then depriving the community, and just in the socio-economic sense, also stupid. A rather lengthy argument could be made here, but in brief, the pure capitalist system not only is a myth, but the pursuit of it is highly detrimental.
Conclusion: if you were really an intelligent entrepreneur, you'd get a real job, and spend your time in NH trying to help others.
Now, as for the problem at hand, the only way changes can be made, is from the side with market power. And in the case of rare items, that'll be the sellers.
