The court will have no problem allowing regulation if it so chooses. They'll define what a "vibrant and free market" is and they'll define what "unfettered" means. Rather than interpret the words in absolute terms, they will presume the words can be qualified (by themselves), and will invent "tests" to determine whether a law meets their invented standard for vibrancy, freedom, and unfetteredness.
This was struck down not to long ago under the name of “Net Neutrality” not likely a go again. Same crap in a different wrapper.
