Just because Amazon sucks, does not mean we need to retreat into full-on anarchy over this. Craigslist is also a marketplace and it isn't the behemoth Amazon is.

Also, Amazon provides a lot more than just a market-place. Everything from "inventory tracking to tax collection to credit card processing". These are no trivial features.

You could have started a regular, centralised, open market-place - by the community, for the community type of deal - and get the same benefits. Of course, selling "medicine" would be difficult.. but we all know that is not what this is about, right?
