Come on, the planning controls we have in the UK are a good thing in the main, allowing people to do what they like with building and extensions would lead to monstrosities.
We are not alone in having strict planning guidelines, I believe that it is similar in France, Germany, Switzerland and Austria.
The limitations on Dish size affects a very small percentage of people, it is really only hobbyists who require bigger than the sizes in the guidelines and even then it may still be possible to excede these with planning permission.
If to be like the rest of the world means allowing planning anarchy, then I think I prefer us being different. ;)
