I've pushed for this before. Your idea: haven't read linked article yet. Mine was an organization that obfuscated working- to middle-class finances as much as rich. It would operate at cost with most legal stuff done as templates and accounting comouterized. It could be a public-benefit company, foundation, or co-op. They'd just charge annual fee to be in, consulting for anything complex, and everything external at cost plus minimal labor.

What yall think?
