Just one more note. You mentioned that the bitShares assets (bitUSD) mathematically go to zero, assuming blockchain adoption. The opposite is actually true. BitShares stable assets are backed by BTS, which gives credence bitUSD market as the price of BTS increases. Theoretically, as BTS goes up, the tighter the bitUSD peg.
I truly believe that EOS can bring about a relatively stable currency through liquidity across decentralized exchanges, but those exchanges will need to be able to handle futures contracts to eliminate black swan events.
bitUSD is pegged to USD, a debt-based currency. When USD goes to zero value (see note 3), bitUSD or any USD pegged token will follow by definition, even if it is backed by collaterized currencies that have value (it will take less and less bitshares to support a near zero valued USD). Moreover, future contracts are debt-based economical tools that will easily be replaced by smart contracts in a value-based (blockchain) economy.
