I appreciate your comment and the perspective. Yes, a corporation is legally an artificial entity, but what that really means is this:

"A corporation is a pile of money to which a group of men swear moral allegiance." -Wendell Berry

The "artificial person" part just means that when the shit hits a fan, there's a line of lawyers standing between the group of owners and the fan.

It's still property ownership by conscious humans, even though our system has created a bunch of police security cordons to keep the public from having access to them with pitchforks and torches.

The same thing would apply if you gave 'ownership' to the natural environment: people and lawyers would actually be acting as proxies.

My point was that they should be acting as proxies for real people who will exist in the future, rather than for trees and animals that could be either respected or not, depending on which bully takes over the lawyers du jour. If ownership is assigned in perpetuity to the 7th generation, then they will never be present to sign away their rights, so once the rights are assigned, they stay there (in the future) as long as the legal system is in place (not a high level of confidence at this point, anyway, so there's that....), and you have a better chance of selling the idea as "for the grandchildren" than for the rabid raccoon, mosquitos or hungry bear that is chewing its way into the house every night.
