I cannot agree with your argument that hackers will drive crypto users back to the banks. The banks themselves are regularly hacked.

Governments will not save you either, they are more sloppy than the banks are with cyber-security.
Think Wikileaks, Edward Snowden.
The standard institutions are mostly powerless because they simply do no comprehend the issues, as they have vested interests dictating their policies over the needs of voters.
Think the death of Net Neutrality.
Demanding governments to take action invites the Orwellian Big Brother Police State in through the front door. They themselves are running the biggest hacking operations that exist. As Edward Snowden pointed out, these multiply the hacking problem, because once discovered by non-government hackers, these are backdoored reused.
Rather, the course of action is, as you were forced to do, educate yourself and take action.
