We don’t know if Queen Elizabeth had the same arrangements.
A government with a still active monarchy will seek methods to quietly and graciously fleece the economy so as to maintain this monarchy at royally high standards of living.
The exact same thing is the law in almost every state of the USA. Don't know about Louisiana because their law is weird, but unless escheat has been abolished in the state constitution, it's still the law. Usually here there's a "grace period" to reclaim the property if an heir shows up.
No, we don’t know. What we do know is that HM Queen Elizabeth II was strong in her Christian Faith, unlike Chuckles.
Personally, I was a strong Monarchist with Elizabeth II as Queen. With Chuck in charge, no thank you. I wish he could have been convinced to just abdicate and let his boy be King. William seems to have inherited much from both his mother and grandmother, little from his father, which is a good thing.
