This is right. Lax security practices at a bank are "more acceptable" because stupidity can be partially compensated for. Stealing money from banks, even if you have the ability to spend it for years is very risky, can be turned back (for losses of banks and governments, not, of course, when normal people get hacked/scammed/...)

If we are to have currencies beyond the reach of laws and courts (which seems to be the point of bitcoin and the like), we will need actually capable organizations.

I wonder what countries and governments will do ? Because we all know that they won't actually have good security practices.
