no, actually that question ((why would the moon be physically 'lawless' when all the rest of creation is apparently physically 'lawful')) is like asking why would God create something completely out of character for God -- it's asking, why would God seemingly purposefully create deception?
everything measurable and observable in our universe points to and 100% agrees with an heliocentric solar system with spherical planets & moons. nothing measurable and observable in our universe agrees with or points to a frisbee earth.
God has given us all kinds of evidence in His creation and given us intelligence to sort out how His creation works and is designed. 'flat earth' models propose that all the observable and measurable evidence God has given us are lies.
there is no flat earth model that explains the moon, but the heliocentric, spheroid-heavenly-body model explains it perfectly.
what flat earth suggests is that God has intentionally deceived mankind by the nature of His creation.
that is not asking, 'why is God good' -- flat earth begs the question, 'why is God evil?' because it makes Him a creator of lies.
lol ok...
planets, moons, the sun at the center of a system, and gravity were not 'invented' in the last 60 years ((NASA has only existed since 1958)) -- they've been observed and described by mankind for thousands of years.
