Adrian-X: both are correct - Alpaca John solution is wrong; Myrkul: solution is correct but insufficient. (Solution the property, given by God or the gods, or the big bang, [land air and water] is redefined in a new meme as something other than a commodity)
This is interesting. Now, which meme would you prefer replaces "Two objects cannot occupy the same space at the same time, therefore, space, being scarce, must be allocated, and the fairest means of allocating space is that the first occupier has a better claim than all subsequent claimants, and this claim can only be transferred voluntarily," ie, private property, homestead principle, and voluntary sale?
And, given that the current understanding of voluntary trade is founded on that meme, how would you structure an economy based on your meme?
