Sorry, but ruining your kid's future by sending them off to an unlicenced school where any nonsense could be taught as fact by entirely unqualified people, without even so much as basic child protection assurances is not a thing in any civilised society.
That's how child abuse happens, that's how religious indoctrination occurs, that's how kids get to adulthood and realise they have zero useful qualifications or skills and their best opportunity for education (and quite literally "learning how to learn") has been squandered through no fault of their own.
Yes, sure, what's wrong with a closeted billionaire running a unannounced secret school for children and not licencing, meeting child protection obligations, or even telling anyone that the school exists, let alone who's teaching it, and keeping the whole thing hush-hush and off the record books? Can't imagine THAT going wrong at all...
