Arguably the same thing blockchain tech got away from — a primary stakeholder with a "monopoly on violence" (i.e. a government with armed police et al). If you attack the US banking system, they will stop you in quite short order. The FBI doesn't screw around. If you attack the blockchain, well ... uh ... the owners will ... be really unhappy with you? Realistically you're only in trouble for doing that if you're pissing off someone else with "the means to violence". If you screw up money laundering operations for a cartel, then what you're likely looking at is acts of violence between two criminal organizations, but if one of them has the upper hand, they can basically act with impunity. When you're looking at the "small fry" – individual people with their own bitcoin/whatever stakes? They're just fucked. It's true if someone steals your wallet, but it's also true if someone torpedoes the whole system. That's the cardinal problem with all of these blockchain technologies — by deliberately designing the whole thing to disintermediate the authorities; they accomplished exactly that: there are no authorities to deal with systemic problems.
