Most of those 10 people don't get the item they are looking for. If 1% of 10,000 people want a particular item each week, then you have 100 selling in a week. That's a decent amount and a crafter can cut their own niche in the market here, so these items might sell again.
A lot of crafters, for convenience sake alone, like to play the market with only a handful of specific items at any given time.
