The main problem with Distributism is that it fails to give any guidance for economies once economies of scale become feasible. It harkens back to the days before the transportation and industrial revolutions made it possible to produce large quantities of goods efficiently and for people to get access to their portion of a large quantity efficiently.
That's the main problem, imho.
It reminds me of the propaganda of many conservatives in the 19th century, to save artisanry and small trade from being ruined by modern capitalism.
But you can never turn back in time, even though I also have a soft spot for small and pre-capitalist economy. We have to get
beyond capitalism, not to fall back behind him.
