If every permaculturist who has $199 extra put their money and this essay into the contest, and they had to choose to give it to everyone who submitted this essay (since obviously it's the best essay

) then that would be a really cool way of crowdsourcing a house. If others who have no in depth knowledge of permaculture but want to support the cause submit to the contest, then that increases the likelihood further that the house will be transferred. It's an opportunity for permaculturists to share the monetary cost of transforming the world across a broader array of people.
Of course, it could just get given to some jerk who writes meaningless drivel, but better to have tried and lost, yes? and enough repeated entries of the same message would get a lot of people's attention.
The age of contests is really over. The age of cooperation is upon us. It is no longer a matter of idealism, it is necessity. Might as well quit fighting reality, yes?
One other thought--although the contest rules certainly do ensure that they get market rate for the house, they also still allow the facilitation of more communication about who is best suited to become the new owner than if it were simply handled by a real estate agent. Interesting how this system alters the usual way of giving the house to the person with the most money--now it's the person with the most eloquence.
Take my words and use them to win. I know you'll take good care of the land. They can be made more powerful, revise it and make it your own. May the best-suited homesteader win.
