Is LEGO Troll on the Loose a good investment?

Why is LEGO Troll on the Loose so expensive?

Troll on the Loose was released in 2002 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
