In practice for this particular instance, I agree with you on the correct policy position: the amounts of real-world money that would be being put at risk are small compared to the real estate bubble, and the financial nervous centers of our economy are more insulated from this bubble than the one in 2008.

I do think your general principle for appropriate government action is too strong and leads to some questionable results, but that ends up getting too involved in abstract political principles for this particular thread.
