The post has nothing to do with inter-state commerce. Its to do with Federal Laws set by the Indian Govt, which overall seems to be deeply protectionist. If you ask any historian the reasoning for this attitude in India and why its tolerated - is mainly because of the holdover from the time India was colonized by European Powers.

Essentially what I am saying is that its not easy to sell 'Free Trade' in India.

I wasn't blaming anyone for anything - just staying the facts. I personally think it would help India to loosen up some of its protectionist laws and be a little bit more like China - but that is just my own opinion.
