What type of stuff would they need in a perfect world? If the weather was perfect and the animals were friendly and food was abundant and free and everyone was vegetarian, what would they need? They wouldn’t need houses to be protected from weather, climate, or animals. I don't see why they would need buildings of any kind! If the earth was producing enormous quantities of food from pole to pole, they wouldn’t need tractors, plows nor a highway system, nor vehicles to move food and goods from one region to another. They wouldn’t need lots of things we need for survival and protection today.

Technically, one drop of water would cover the planet, if you spread it really thin.

Would you send your children into any hostile environment like the moon, a battlefield, or the bottom of the ocean without proper protection? To send them to the bottom of the ocean without properly working equipment like a submarine or scuba gear would be murder. The same would be true about sending them into battle or to the moon without training and protection. Be sure they are properly trained and equipped to handle the errors they are sure to face in the public school system.
