I think "Sure, any regulation will have bad side effects" was the rallying cry of the SOPA backers
To continue your SOPA connection, "Google will go out of business if SOPA is enacted," isn't a good argument in and of itself. You're assuming that Google staying in business is a good thing.
Arguing against regulation of X because companies that have built a business around X being a certain way will go out of business necessitates that an explanation of why X continuing on in the same manner is in the interests of the general public.
As an example, stopping terrorism is generally seen as a good thing, yet opinions differ on whether the laws that purport to prevent terrorism are good, and the government has also used such laws (such as e wire tapping allowances) to justify non-counter terrorism ops.
I think my point is: "if we don't implement SOPA, we (the companies) are all gonna die!"
Don't know how to express it in general, but I hope I can make my view clear.
