Yeah, the opposite works too, if people see RPGs as possible entry points to the larger audience games, then RPGs still have value to the larger audience industries like Cardgames, Boardgames, Novels, Video Games, etc...
We need to get RPGs to the point where they are considered a respectable and viable tie-in product for transmedia IP's. They have a function as a Venn set that intersects with every other form of entertainment known, but I don't think they are considered to have the value they do.
I know people who do cardgames but not boardgames, or buy video games but don't read a lot. I've never met a single RPGer who doesn't do all of the above to some degree. If I can sell you a RPG, chances are I can sell you a cardgame, boardgame, movie, book, comic, or video game on the same material, and turn you into a proselytizer.
Roleplayers take such a weird pride in not being worth anything to corporations customerwise, they ignore the fact that they probably are a very key demo out of scale with their numbers.
