Sova, desert, shemitta

Private property says if a man finds the resources and creates a product, it is his and he earned it. 

1. From a sova perspective the resources are not there to be found and claimed as one's own, they are there as a gift of grace. 
2. The person's productive power is itself there in part thanks to God's grace. 
3. Beyond the sova point the surplus belongs to the lower classes during the shemitta year.
