As time goes on he will feel lonelier. Lots the aides, pals that have helped over the years- were old school, posh, brits….who were a bit older than him. Even his head security guy (again British) that he’s used for years….that guy must be well into his 50s. He can’t be an on the ground security operative forever.
They will be replaced by Americans, who quite rightly, will pay no deference. Who won’t know the rules of the royal world. He’s hanging onto the last threads of a Royal life but that won’t last forever. He will always be rich (Meg is bringing in the cash) but he will be completely removed from everything he has ever known- family, friends, aides, royal estates, royal/aristo/English culture, geography.
Sentebale, with all the old staff leaving and Harry too, is symbolic of the royal cache that’s he’s been coasting on the last 5 years, coming to an end. I also don’t think Invictus will be around in 10 years either.
He will be a househusband of Beverly Hills.
