I've worked at private companies where we've had cesium atomic clocks in the lab. I've owned a rubidium atomic clock. I'm not saying that shutting down WWVB/WWVH/WWV isn't foolish, but atomic clocks are readily available to anyone who wants to pay. Cesium is high five figures and rubidium is often available for under $1,000.
