Italy has 58 million inhabitants. At 280k/year, together with the 8% of immigrants already there, such a policy would reduce native Italians to just 62% of their own country in a mere century. However, that ignores their sub-replacement fertility, which would probably see them become a minority in this time, in what used to be their country.
Italians themselves evidently don't want their grandchildren to lose claim over the only country they can call home. But because their food doesn't pass some ridiculous purity test, the author believes their desire not to share Italy with the whole world is illegitimate?

I don't even know what this is supposed to mean. "let you come"? Are Italians flooding into Nigeria? And are Italians to hold Nigerians accountable for the use of their innovations, culinary and otherwise? A brief glance at https://en.wikipedia.org/wiki/List_of_Italian_inventions_and... suggests that would be a lot of "accountability", as it includes such things as the battery, pasta industrial production, television, the typewriter, antibiotics, and germ theory. I'm truly confused what accountability should be demanded for learning from others.
