For banknotes in 1840’s America, read non-corporate electronic markets today. Anyone can start a marketplace and establish some perceived advantage - in pricing, positioning, pools of users, or technology - over competitors.
That creates endless confusion for users and makes the cost of achieving lasting dominance over other players untenable. Some niche sectors are well served, eBay is the New York farmers’ bank of its time. But the muddled, time consuming, nature of online trade means most transactions occur without it. Outside of the corporate sphere we don’t yet know what this technology could do for us because its potential has always been so dissipated.
As with “detectors” and “shavers”, attempts to resolve this confusion tend to become part of the bewilderment and add unnecessary overheads for users. Think of the countless portals, directories, consolidation sites and ranked-by-users sites with grandiose claims but, in reality, access to only a sliver of the market in each of hundreds of online sectors. Except in small niches, no-one can break out of this cycle of potentially useful services being eroded by dozens of start up competitors as soon as they appear to be succeeding.
As with printed money, only one body can create an economy-wide focus for the benefits of this facility by ensuring enduring advantage for one system. That’s government. No entity in the private sector can pass the laws that allow such a service to be underpinned by the highest authorities in the land. Similarly no company has an incentive to create a completely transparent, genuinely accessible, service in even the lowest level markets with fixed pricing for years ahead and any chance of user lock-in renounced.
