Almost all economical models that exists out there always reach a point of indeterminacy. What happens when there is massive inequality in the bitcoin world ?
Money has one important purpose :
1) Efficient allocation of labor for society's benefit.
To achieve it we need to establish something that can be used as a source of value.
Bitcoin solves the problem of source of value but we know from history that it doesn't always solve the problem of efficient labor productivity.
Since by definition society requires centralization to direct its purpose. FDR during the great depression had the same problem of a lot of people having liquidity with no need to direct it for labor productivity.
If we lived in a bitcoin world it would be impossible for governments to mobilize itself to direct resources to solve social problems.

The blockchain is interesting - I think it can solve public trust issues like when it comes to e-voting and reaching decentralized concession. But when it comes to economics it just seems silly that a completely decentralized system makes sense.
