I agree. I think that sometimes you British don't realize that you have the best of both worlds in your royal family. The royals cost you some millions of pounds each year, but they're an investment: you get a lot more out of them in terms of tourist dollars than you put in.
You must know that Americans are completely addled on the subject of royalty, to the point of doing stupid things like curtseying at garden parties. We are a nation of Hyacinth Buckets, however much we prate about equality and democracy, and many Americans go to England to see over the great houses, catch glimpses of foxhunts, see the Changing of the Guard and the Beefeater and all the hackneyed things.
And Americans aren't the only ones; tourists from all over the world come to spend their Euros and yen and what-not there. The foolishness and sex scandals just make it better. You've got a goldmine, and they don't even impose a lot of ideas on you as if they had any real power, so it's ideal.
Mark you, it wouldn't work as well if the royals were dispossessed. You'll note that no one is falling all over himself curtseying to the pretender to the French throne or the Russian throne. Otto von Hapsburg is a lovely guy but too jess-folks, and no one screams when they see him. You have to actually have a current title and live in the castles before tourists are interested enough to fork over thousands in airfare.
I can't disagree about the written constitution, however. But do bear in mind that if you got yourself a written constitution now it would be written with all sorts of silly leftist nonsense in it and so would be worthless instead of the document of beauty and power you long for.
Perhaps you would like to take them back to America, you're welcome to them.

Funny thing, fox hunts are regarded as being extremely cruel by the majority of the British public, and so the elected House of Commons recently passed legislation banning them. However, the unelected House of Lords vetoed this legislation and sent it back to the Commons to be watered down. Of course your average lord likes a good fox hunt!
