A desirable property in a system: it's emergently decentralized.

Most systems, with more use, tend to become more centralized.

Preferential attachment effects mean that people simply use the thing everyone else uses.

What if you could design a system that was the opposite?

Decentralization is extremely expensive and makes changes in protocols very hard; doing it too early freezes the system in place.

You want a system that is not just decentralize-able, but self-catalyzingly decentralized.

The system is always sufficiently decentralized, and the bar for what "sufficient" means keeps ratcheting up as more activity happens in the ecosystem.
