Why do you think Michelangelo’s David shouldn’t exist? That is one of the oddest opinions I’ve ever encountered in my life.
As time progresses statues have a nasty tendancy to become objects of worship as their original stories are lost and replaced with new ones or greatly exaggerated. Once something is raised to the point of worship people will begin doing what they think the idol wants and as a theocrat this is concerning, as it splinters and corrupts society's morals.
