There are a number of fantasy stories where the protagonist is very good at something, largely because they work hard at it, and then they enter a magical world and discover that their skills and work have a lot more impact. Often they have to work hard after they get there to apply their skills. Often the protagonist is a computer hacker and their skills, which in our world only work inside of computers, in a magical context can alter physical / consensual reality. (Examples: Broken Crescent, Web Mage. There are many others. Arguably this pattern goes back at least to The Incomplete Enchanter though success came way too easily for Harold Shea.)

So I think the appeal of this type of fantasy is partly that big effects in our world usually require big causes -- capital investment, megatons of steel, etc. -- even after you know the right "magic spell". In these fantasy worlds -- and in some cases in computer networks -- big, widely distributed effects can be produced just by uttering the magic spell in the right place, or by building a local, inexpensive magical workshop using the right blueprint -- e.g. YouTube.
