Does difficulty matter? Any communist revolution will be more difficult than establishing a network of cooperatives. I believe that if there is a desire for Socialism, people will spend the time to establish cooperatives.
We simply talk about different things. Initial funding comes with different risks.
I think established cooperatives should issue bonds for expansion.
New cooperatives cannot issue bonds because nobody can judge the risk. They have to do a startup and sell shares in a company that owns the assets. But why should the founders limit themselves and do the opposite of Zuckerberg and give their influence away by just owning one vote in the participating cooperative?
