I mean, if they would just stop launching the water via rocket into the sun after using it then it would not be so bad. I strongly suspect the water could somehow be re-used. Though we might need to spend several decades in r&d in order to figure out how.
That's the joke OP is making. Some people (albeit usually teenagers) legit think that water is a nonrenewable resource and once it's used, it's gone forever.
