I and a lot of us would never consider camping near a house. I would rather be miles from anywhere. As for campfires, I only use them to cook food and sometimes heat at night if it gets cold, and I put stones/rocks around the edge of the fire, and when I put it out, I stay there for an hr or so, just to make sure there is no burning embers.
If people keep camping near houses and lighting fires they can't control, you might find the Scottish Parliment reversing the law, adn that would be bad for all of us
