I'm also not sure, but I think he is saying that free education led to Hitler and World War 2. I think he missed a couple of things in history class.
Is there land for everyone? Most of it already is or would go into private hands without governments, so you would still have rent/tax whatever you want to call it.
The only reason there were land laws or private property or slavery was because of laws written by the majority. One stoke of the pen and slavery could have been ended. Hitler was a product of debt, war, and private land. If he died on the streets no one would have cared. He chose another option.
