Is crowdsourcing a form of participatory governance?

Peter Moskowitz’s Crowdfunding is evil for public goods raises an interesting question about the limits of participatory urban governance. From a philosophically informed perspective, I found it striking and worrisome that we can now see crowdsourcing projects for infrastructure projects (e.g., for maintaining roads). After all, even traditional liberal authors like Kant saw it as the duty of the state to take care of the basic infrastructure: „Build good roads, mint sound money, give us laws for exchanging money readily, etc.; but as for the rest, leave us alone!” (Kant, Conflict of Faculties)
