Nation works on artist, artist works on nation.

No artist exists within a vacuum.
The process is symbiotic.
Blood is both Body and Spirit.
A cosmopolitan anti-Nation has no 'blood' of its own, and no art of its own.
Its people are mixed and botched, its highest value is Gold not Blood [lesson in Wagner's Ring].

It is different in a true Nation bound by Bloodlines and a Common culture, an Order of Rank and inherited Myths; here understanding doesn't even NEED to be put into words!
But when it is!
Nation works on artist, artist works on nation.

the truly great artists are all held in high esteem by their Nations.

Italy without Dante?
Germany without Goethe?
Greece without Homer?
Shakespeare transcends everything in England, King or Commoner.

And yet there is not a more patriotic writer.How is that?Because the Nation has formed itself to Shakespeare as much as Shakespeare wrote around the myths and history of Nations

They are the most precious things that the Nation possesses.The whole reason for a culture to exist is to produce a Shakespeare.

So, how to make sure the Nation is 'fit' enough to give birth to such a one; that is the the question Nietzsche's philosophy seeks to answer.
You certainly don't get there with Democracy, equality, pop culture, and the rule of money.
Of course, you have to be a Nation with an ancient tradition to appreciate this.
