Religion exists in a multitude of forms across the planet, many without formal structures. The revelations across the globe surrounding abuse of power within formal religion organisations suggests an erosion of fiscal surety could benefit both worshippers and religions by decentralising power and returning faith to an exclusively spiritual practice, unconcerned with fundraising, capital accumulation and the resulting power these bring.
Large centralized religious institutions, like the Catholic Church, are more able to cover up scandals and problematic behavior than more decentralized groups through a wide variety of mechanisms afforded to them by their large networks and bureaucratic capability.

Decentralized religion makes it harder for churches to spread their message.
