is it possible that many people uniting could beat the big money?
Probably. It just isn't likely.
Surely one of the biggest problems would be the temptation to become the big money.
People already have united countless times over the internet as an entity called anonymous, but as this united being, they would never do anything for a cause. They're content to harass whores on stickham by the thousands, then find out where they live and order them a pizza after making them cry.
It would seem that large groups of human beings united over the internet don't really do anything that makes much sense.
