Good research is usually applicable in other places as well. For example, this "frivolous" research such as understanding sound might translate into advances in sonar or sonic weapons or sonic manipulation, and "frivolous" research into soccer player dynamics could translate into better AI for robotic warriors, UAV's, etc. People researching pointless game theory for making Checkers AI can translate into improvements in AI such as robots that can play Jeopardy or outsmart opponents on the battlefield. Even completely unrelated things can be useful when there are mathematical or computational similarities that aren't obvious at the surface. For example, the problem of moving a jointed arm is essentially identical to the problem of reconstructing a 3D camera, and it might be solved using a technique that was originally invented as a path-finding algorithm for a soccer player. If you only fund research specifically related to, say, military designs, then these happy accidental discoveries wouldn't happen so much and fewer people would be interested in doing research in 1 particular area that is deemed "worthy."
