We can focus light waves , sound waves, x-rays, etc. Why can’t we figure out how to focus gravity waves?

  We can do a lot of stuff with energy in various forms but gravity is just from mass which is quite difficult to control. Essentially we suck at fission and fusion at meaningful scales and we have a very narrow capability as well. I mean, to destroy mass equivalent to Mars in a short time frame is a cosmically cataclysmic nuke, then to not waste that energy, so you efficiently capture it and recreate the mass elsewhere in one huge fusion reaction. Maybe I talked past you and just daydreamed about Dr Manhattan stuff, maybe what it takes to emit gravity at will at some location, is much more difficult than just redirecting it which I dont have the tools to daydream about.
