Of course you can stiff the legal system. But you can only stiff it so far. I Googled "Ethereum steal" and the top three results have figures in the millions, through something as straightforward as a 51% attack. No court system can simultaneously claim to be fair and just and legitimate, and let slide a $1.1M USD theft. And in such situations, other people usually have a bone to pick with said thief too, bolstering resources on your side. If a cryptocurrency scales and somebody pulls off a Madoff-level theft (>$64B USD), could you guarantee some amount of clawbacks by technology alone? I wouldn't bet on it.
