It's a question of whether we even need to attack it.
Bitcoin being there as a "lifeboat" - an alternative to once this whole thing blows up - may be enough.
The existing financial system already is on a one-direction street that goes to ruin
In our current system, money creation and money destruction is mainly done through private banks. New money is created when these banks create credit, and through fractional-reserve banking they only keep a small fraction of deposits in reserves.
The financial system then becomes hopelessly intertwined - if too many borrowers default on their loans, the entire system will fail – even for customers who never agreed to have their deposits invested in risky schemes.
This intertwining creates terrible incentives through a severe disconnect between risk and reward for the financial sector.
The government becomes obliged to bail out banks once they get into trouble from risky lending, which drives banks to take even more risk knowing that their potential losses are capped, but their upside is not.
