That's a strawman of what GP said. Of course technology can't solve humanity's flaws. The point was that smart contracts caused many problems they weren't meant to, which was exemplified by the DAO hack. Smart contracts failed to deliver on their promise and the fallout proved that when it came down to brass tax, nobody with skin in the game would respect a smart contract's execution anyway.
