A big multi-billion $ business deciding to dictate its own behavior or end is not the same as dictating law, even if the law reacts by changing in order to preserve the business.
The current system, where corporations often actually, literally dictate many laws is a lot less open and straightforward.
Big multi-billion $ businesses can only exist in a society where a big government can enable them using bailouts, quid pro quo campaigning and cost-prohibitive compliance for frivolous regulation.
From a societal POV, big anything is bad. I wish more open-minded people could recognize that fact.
That's not true at all; many (probably most) huge companies have never received bailouts. Compliance is also a tricky issue - you don't want to let the market compete on nuclear power plant design without some sort of supervision, even if the current system doesn't work very well. Lobbyists are a different story, but Google, for example, or Amazon, got to where they are without leaning on governmental support or anti-competitive laws.
You want a big multi-billion $ business to start dictating your laws?
Good luck on that one, that's not going to end badly is it?
