A desirable property of open systems: not decentralized, but decentraliz-able.

Decentralized systems are extraordinarily hard to change, so if they start big you had darn well better get all of the interfaces between components right!

Decentralization is expensive, so don't pay for it at the start if you don't need it.

Instead just design your systems and incentives so as it gets momentum, it will naturally get more decentralized.

A decentralized-able thing can grow and the interfaces can evolve as they grow and become more decentralized.

Ensure your system is minimally-viable-decentralized to start, and has clear buds of decentralization to bloom as the system does.
