Eh, that's pretty specious reasoning. If I start a business selling space water cannons that anyone can use to spray water at the ISS as it flies by. If these cannons are consuming whole farms worth of water in use and just blasting it out into space, you can still be mad at the water waste because you think that water could be put to better uses like growing animals for hot dogs and chicken nuggets, and not fleeting entertainment for people to have interplanetary water fights.
