Actual economic scarcity is pretty much the only business model, but I think you are using the term differently. A profit-maximizing enterprise should be looking for market clearing volume and pricing. Produce more than the market will consume at a given price point and you have excess inventory; produce less and you leak your potential profit into the secondary market.

I'm pretty sure there is value in creating the _perception_ of scarcity (nee exclusivity) for one's product... but that should also be conveyed in the price.
