So money is the root of all evil. We knew that. What can we do about it?

Not any more. Money and barter were required in times of scarcity. Today we live in abundance. There is enough for all to thrive. Totally sustainably. We now have the knowledge and technology to provide easily for all human need. Without war, poverty or exploitation. There is no shortage of land, food, building materials or the capacity to produce the things we need.
