Not really, if markets converge to the point where you have just a handful of large warehouses, you nationalize those warehouses. If the private sector can create more warehouses and have such an edge that they can beat the government run ones then encourage them to do it. Whatever groundbreaking technology comes about fifty or a hundred years later that brings them to a new monopoly or oligopoly, you nationalize that. When markets are working in a healthy way and there is a lot of competition, you have taxes and a UBI. When markets aren't competing and you have a handful of oligopoly companies, you heavily regulate them or make them publicly owned.
