But it seems that some of our detractors are defining as a "scam" any scheme in which an asset's value depends on the availability of future market participants willing to buy that asset. By this metric, almost any imaginable token, currency, or good which can be resold is a "scam", because its value depends on people being willing to buy it in the future! This is an incredibly broad, useless, and non-sensical definition of "scam".

This^ is a very good point. Thank you for that - I'll definitely use it to strengthen my argumentation when introducing new people to Steem.
