I can't see any advantage to them from the the tabloid media's obsession. Other very rich people seem to get along happily without that kind of attention.

The occasional ceremonial occasion, like Presentation of the Colours ,or the Tourist stuff like the Changing of the Guard, and the trickle of Royal Visits to hospitals would be quite enough. The tabloid gossip rubbish, I cannot imagine why they can benefit from, still less enjoy.. My impressionis that most of the other royals in Europe don't have too much of that, and don't miss it.
