I couldn’t tell you what’s wrong with them from n engineering perspective, but from a user perspective the guidance rarely worked correctly (a scary possibility with artillery) and the system the gun was retrofitted with just wouldn’t function a lot. As far as cost, if Raytheon was selling that gps guided drone to the government, you can bet it would cost orders of magnitude more than the consumer version. The military industrial complex is not a myth.
