You`d have entire states barging into one another spurs clicking, is why. Painful for the population really.
Particularly, now that India has exported zillions of copies of The Kame Sutra to the U.S.
This had to do with human trafficking where people mainly poor women and underage girls were tricked into starting a life full of oppurtunites in another country only to be realised they were sold into slavery and prostitution. They would be threatened, beaten and forced to have sex against their will and get very little or no money. Finding help would be difficult as they do not know the language, do not have access to a phone or they are scared to run or say anything as they would be constantly followed. Some people had no choice and needed the money so they became prostitutes and some are forced like I just mentioned earlier. It could also increase the levels of anti social behaviour in the area.
