An increasing number of communities successfully governing urban commons could be seen as a strong move towards ‘delinking’ from homo economicus myth that still remains at the centre of the capitalist economic assumptions. This paper, theoretical in nature, presents an alternative, a preferred scenario of a future 'communal system' as a vision of society built on different values than homo economicus conduct, values that are distinctive for urban commons today, especially in peripheral countries. These are: responsibility, networking, cooperation, caring for others, reciprocity, self-help, continuous learning and sharing. The given three examples of urban commons: Torre David, SE VIOME and Bangkok Noi urban gardens - that illustrate such system in the present - share these values and therefore contribute to social change. Although commons are still at the margins of economic considerations, while corporations through the processes of neo-colonisation dominate the centre, a future transformation into a 'communal system' is possible, as posited by the postcolonial theory and the actor-network-theory (ANT) discussed in this article. Vision of an economic system, based on the new communal myth contributes to the emerging field of post-capitalist, post-growth theories arising in the shadow of a climate catastrophe and other upcoming crises.
