A common blockchain criticism is "why can't we just do this but without speculation?"

Is there a good layman explainer we can link to on why blockchains require a native token with financial value?

A doodler and computerer. I like permissive/permissionless open source, smart contracts, p2p systems, room-scale VR, and NixOS.

It’s not easy talking security and incentives with casual humans   

But I think blockchain stuff can probably become pervasive with most people having zero intuition about how it works.
