The larger a network or computer system, and the more centralized, the tougher it is to protect against catastrophic takedowns.
More elements and people results in higher probability of break-in. More centralization means more damage/loot in case of security breach.
Big, centralized systems thus equal high security risk.
Throw into that the decreasing effectiveness of state security enforcement, it might look a little… bleak.
The solution? Decentralization, down-scaling, crypto-anarchist security (read “legal”) systems.
