The problem is that (the way Naval treats them) each of the main variables seem arbitrary, but could easily determine whether the economy you create is viable.

In Bitcoin, though the system itself is "trustless", participants trust that they are all treated equally according to the protocol & open source code.
In the case of a startup raising funds, you wouldn't get the same sense of altruism. The incentives are not aligned for the major players: the startup founders, the protocol developers, the other coin owners/shareholders and the miners.
Should an arbitrary pre-mined amount be set (as the founders' equity), and simultaneously be non-threatening, what is to stop the network from invalidating the pre-mined amount at will?
If it were instead threatening, why would miners be interested in spending compute power?
Naval also writes of supporting the open source developers with transaction fees. Unlike the commodity on which the coins are based, these are not easy values to calculate.
Certainly there are a lot of possible new models, and autonomous corporations are very exciting. I just don't see how you can add a founder-controlled, for-profit startup to the other players in a crypto currency ecosystem (the miners, the non-profit developer foundation and the coin owners) and get something that works.
