Is it appropriate for the university library to have more collections than national library?

Why wouldn't it be? Who is going to be the policing patrol visiting universities and demanding to examine collections and write them up for having them? Who is going to create laws to stop them, cities townships counties states the federal govt? What are you going to call the laws preventing ownership?

Who is going to stop alumni from donating money to their alma mater so the school can purchase collections? What law says alumni cannot make their school a beneficiary in their will giving them ownership of things they have collected through their lives to benefit the school? Who has the right to tell philanthropic organizations or a Bill Gates (for instance) philanthropist that they cannot donate money or buy collections and donate to a university they happen to like???
