I have some sympathy with that view - it's not a life I'd choose and I'd run a bloody mile from any kind of public life - I think the problem they are going to have is that they don't appear to be running away and living a normal life on a farm in Manitoba a days drive from the nearest shop, they seem to think they can live a kind of hybrid Royal/Celeb/private life where they are Royal when they choose to be and private when not, only dealing with favoured (and presumably high paying) media and on their terms, and also being a commercial entity.
It appears to be a very badly thought out plan with little room for anything but that which they wish to be true - no thought for the Recency Act, or their security costs and who will pay for them, no real thought about how they will navigate the rather difficult line between Royal, Celeb/influencer, and private family apart from 'everyone will love us!'. I'm afraid they will start off as a hybrid of the Duke and Duchess of Windsor and the Kardashian, and end up as Katie Price.
