England is a very crowded country with most people living in towns or cities. It is also a democracy where the majority elects the government, most of the time anyway, but I don't think English city dwellers plan to ban our hobby. While every year a few flying fields are lost, clubs usually find somewhere else to fly and though I'm not a great enthusiast for electric flight, there is no doubt that the growth of electric flight has saved quite a few flying fields or at least reduced the propensity for opponents to complain about noise.
The most urbanised nation on earth is Australia. It is also a democracy where voting is compulsory. I don't think that the future of the hobby is at risk there. Mind you, outside the big cities there's plenty of space for us to play in in Australia!
