It's either extremely subtle satire that I cannot detect, or this guy does not understand how the world actually works.

So, you code your contract. When there's a need to enforce something in the real world (which will happen, eventually - virtual only goes so far), you eventually need contracts underwritten by guys with guns (police and eventually army), or whoever feels wronged or doesn't want to pay their share, won't.

And when you need the underwriter to step in - you realize that you interface to them through the court system, exclusively using legalese and lawyer interfaces.
