Fine, but why doesn't every new industry have to make this same argument?

It's pretty obvious to me that social networks have some pretty dangerous attributes (decrease in privacy & personal securty, etc) to them. Do these dangerous attributes outweigh the value that twitter provides? Who decides and why?

Because most new industries aren't within the financial industry, messing with the fundamental operation of markets. Those that are have to make that argument.

I think every new industry does have to make this argument. And they have to make it to their industry regulators and to the people who employ them. That is we, the people.
