They solved the comms problem on Mars with relay satellites. Would those be harder to use, around the moon? "Habitat space" is useless unless you can get there

They solved the comms problem on Mars with relay satellites. Would those be harder to use, around the moon? "Habitat space" is useless unless you can get there, and if you can get there, you can get back to Earth. To disprove it, you would need to find something useful for SLS to do. NASA, of course, has no say in whether to use SLS. Congress decides that. The best NASA can do is have it not ready to fly. The longer it takes to fly, the fewer flights they will end up forced to do.
