The benefits I see are a looser organization, more emphasis on individual involvement, less structure required, security of centralized funding is not a concern, less tools need to be built to make this a reality. Really, the only things we need are some sort of escrow system where individuals can lock up funds towards a goal, and release them once they are satisfied that it has been accomplished. I think this will also lead to a more organic growth, as we'll only be able to do things we can raise the money for ourselves. One problem I saw with this, is that it would be difficult to raise funds for projects since there would need to be an active involvement on the part of every participant to release those funds once the project has been completed. But the solution to that problem seems that if someone wants to pledge towards a project, and then not be involved further, they would just add to the pledge of someone who is more involved, and they will release it when the time comes.
