I'm not particularly interested in debating what exactly independence means in the abstract. But to my untrained political eye, it seems that countries are free to choose political and economic unions and those unions tend to come with benefits and obligations. Are members of the UN or WTO independent? If a body consisting of representatives elected only by "Scottish citizens" can decide which unions to associate with, and which to leave, we'll have independence in my book.
