I think this is a very astute point and absolutely true. I don't think Harry previously realised how much was done for him (clothes, trips, charity ideas, events, patronages etc etc) and I think that's why they struggle to get anything off the ground now. They, and especially he, are floundering without the sophisticated infrastructure he used to benefit from (without recognising that privilege, obviously).
More generally, Harry these days wears the permanently baffled look of a man who can't understand how he got to where he is. And indeed it's difficult to overstate just how drastically he's imploded his own life.
He made the marriage to Meghan against the advice of three separate groups in his network: the Windsors, the Spencers and his old Etonian friends. That's three separate groups so he can't blame it all on Windsor racism.
He then destroyed his entire blood family relationship AND most of his friendships AND his ability to realistically live in the UK, his homeland AND the love the UK public had for him. PLUS, Invictus has lost a lot of gravitas due to his antics and is in financial trouble. PLUS he's an international laughing stock.
I mean, the silver lining will of course always be his children. But it's still a staggeringly enormous price to pay for pushing ahead with a marriage to someone he'd been dating for just a year.
