Trying to protect against another mortgage meltdown is just ambulance chasing, at current liquidity markets are inherently unstable and highly sensitive to the number of trades[1]. Since HFT artificially drives up the number of trades, but despite this is orders of magnitude away from providing enough instantaneous liquidity, taxing them to death makes sense.
