There are multiple reasons to kill the goose. one you could get two goose by killing and selling one, you could get 10 years of worth gold eggs by killing one. Sometimes it's more profitable to kill and sell the goose than waiting next 10 years to get same amount of golden eggs.
It's not why to kill the goose! it more of "it is profitable to kill the goose."?

Don't get me wrong. I really like this project. I really hope to see this project to shine. that's why I wanted to bring out my concern. I would hate to see this project to fail!
