Decentralization has an inherrent trust basis that is taken for granted: no trust has to be invested into any individual person.  Yet once any system can be abused it will be, so there always has to be someone you can trust and with so many coins appearing day by day and the difficulty level in creating them decreasing constantly... a force is needed in the opposite direction, an agreement pursued with personal gain set aside by individuals who agree to trust each other and then stake this trust itself on a blockchain. Fair and equal and also effective.
