I'm happy to hear that yet another piece of "alternative", "stick-it-to-The-Man" payment infrastructure has been burgled. Really.
It injects a much needed note of caution and realism into the dream of technologically focused, realism-challenged (and therefore irresponsible) amateur social engineers.
You see, a large part of the appeal of bitcoin comes from its aura of "under the radar", "the authorities need never find out" financial transactions.
This holds an attraction for several groups, of which two are problematic: outright criminals and their "lets-dodge-the-system" libertarian cousins.
I believe that outright criminals like the possibility of doing financial transactions without giving out your real name. Think "dark net" transactions involving in cybercrime services, malware, botnet control, stolen data, stolen credentials, drugs, weapons, etc. Think suppliers in "Silk Road" transactions.
I think that "lets-dodge-the-system" libertarians, who often figure as end-users of illegal goods and services are attracted to the possibility of doing "under the radar" financial transactions for the same reason: their real name can be kept undisclosed. In part they're happy to purchase illegal goods, in part they're ideologically motivated (as in "we need to grow alternative economy that's outside "government" or "system" control because all government is bad and "the system" is designed to screw us over").
For the first group (criminals) I believe it serves as a useful deterrent, or at least a risk and a complication.
For the second group it serves as a salutary reminder that their fellow citizens are at least as reprehensible as "the government" and just as capable of screwing them over as any "institution". After all, the institutions we have have evolved over several centuries, if not millennia, to strike a balance between freedom, safeguards, responsibility, accountability and free-for-all banditry. Something that starry-eyed, technology fixated "bash-the-system" enthusiasts will only appreciate if hammered home by personal or close-to-personal experience.
Where and how new technologies like bitcoin should fit into our society remains to be seen (and experimentally determined). However, our existing institutions have very real merits and safeguards that have evolved because of human nature itself. Such safeguards (which we all too often take for granted) are lacking from new technological developments and are just as important as the basic functionality. A reminder of which can only be positive.
