"The Wizarding World has aristocratic pretensions (the "Noble and Most Ancient House of Black," pure-blood ideology, old family wealth) but no actual aristocratic structure. What exists is better described as an informal oligarchy based on:
Social networks and family connections
Wealth (when present)
Political influence in the Ministry
Blood prejudice (not actual blood reality)
This is why fanfiction that introduces "Lord Potter" or formal wizarding nobility is canonically impossible - it contradicts the fundamental structure Rowling established"
