Ah, I see that you are catching on to where this is going.
The underlying assumption within our current economic system is that public goods are not monetizable, so a centralized government should provide them. So should we assume that that will continue with the introduction of blockchain technologies? Or would it be possible to have a 'decentralized' government of sorts sort many public goods and services out for us?
