The champions of the "sharing economy" tout two apparently contradictory rhetorics, say Condognone, Karatzofianni, and Matthews. One is of disruptive innovation typical of neo-liberal ideology; and the other is a positive normative discourse about grass-roots and bottom-up revival of community, trust, social capital, and the moral economy allegedly enacted by exchange between peers. This obfuscation has contributed to delays in or total lack of policy and regulatory intervention, they say, so that the platforms have grown into powerful economic and political players with no public or legal constraints.
