What you're talking about is USC 512 (http://www.law.cornell.edu/uscode/text/17/512), 17 USC § 512 - Limitations on liability relating to material online
These are more or less completely unrelated apart from being introduced in the same legislative act (which also did a fair number of other changes to the law.)
First, you're going to be transferring that money to the banks/institutions that lend to them. So the money isn't going away, it's just ending up as profit for somebody else (as compensation for them considering themselves to be taking on more risk.)
Second, the taxpayers going to get rid of that amount of cost in the form of risk; the averaged risk is paid by the taxpayers, it is just paid in bulk when the banks are about to fail.
This assumes the calculations are all correct, and it doesn't count in what indirect cost the economy would have from loans getting a bit more expensive overall.
Stop removing DNS entries; that's attempting to censor things that aren't in the US for non-US citizens.
Require a full court proceeding to stop advertisements and payment processing in the US - ie, no "court order", it has to be a full lawsuit with the ability to defend.
Require the removal of access to only affect a specific, listed set of companies.
Require the company requesting the blocking to pay reasonable costs of blocking.
Remove the making of copyright infringement into a felony; each of these things can easily happen by mistake.
(It's a Linux-specific extension.)
