> a) the intent of the founding fathers was relevant to today's society and b) their intent was to have a limited size of government, both of which are pretty big assumptions.
Their intent for a limited size of _federal_ government is almost certain. And I don't see how it's not relevant: our federal government is huge and almost entirely unaccountable, and clearly is not functioning as it was intended. From Federalist 45:
The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite. The former will be exercised principally on external objects, as war, peace, negotiation, and foreign commerce; with which last the power of taxation will, for the most part, be connected. The powers reserved to the several States will extend to all the objects which, in the ordinary course of affairs, concern the lives, liberties, and properties of the people, and the internal order, improvement, and prosperity of the State.
The operations of the federal government will be most extensive and important in times of war and danger; those of the State governments, in times of peace and security. As the former periods will probably bear a small proportion to the latter, the State governments will here enjoy another advantage over the federal government. The more adequate, indeed, the federal powers may be rendered to the national defense, the less frequent will be those scenes of danger which might favor their ascendancy over the governments of the particular States.
> How would removing an unrelated insurance corporation promote healthier decision making amongst investment banks?
Not unrelated. Gramm-Leach-Bliley removed barriers allowing commercial banks to act as investment banks. That was my point: you can't remove these barriers without also removing the insurance. Having the FDIC encourages commercial banks to be much riskier.

Feel free to correct me where I'm wrong. I think the housing bubble was entirely avoidable had the government taken different action. I'm not saying that it was ENTIRELY the fault of regulation. I do think that: deregulation (including removing the FDIC and SEC), much less Fed fiddling in attempts to 'fix' the dot com bubble, and no bailouts or any implicit guarantees of bailouts, and you wouldn't have seen the housing bubble.
