There is a religious principle: Love thy neighbour as thyself. But it's also an economic asset. If you've got a neighbour, you've got help, and this implies another limit. If you want to have neighbours, you can't have a limitless growth economy. You have to prefer to have a neighbour rather than to own your neighbour farm.
Wendell BerryAs I understand it, I am being paid only for my work in arranging the words; my property is that arrangement. The thoughts in this book, on the contrary, are not mine. They came freely to me, and I give them freely away. I have no "intellectual property," and I think that all claimants to such property are theives.
Wendell Berry
