Access is so superior to ownership, or possession, that it will drive the emerging intangible economy. The chief holdup to full-scale conversion from ownership to omni-access is the issue of modification and control. In traditional property regimes only owners have the right to modify or control the use of the property. The right of modification is not transferred in rental, leasing, or licensing agreements. But they are transferred in open source content and tools, which is part of their great attraction in this new realm. The ability and right to improve, personalize, or appropriate what is shared will be a key ingredient in the advance of omni-access. But as the ability to modify is squeezed from classic ownership models (think of those silly shrink-wrap warranties), ownership is degraded.
The trend is clear: access trumps possession. Access is better than ownership.
