Liberty

Its funny how tke US and UK talk so often about liberty, yet have loads of rules we commonly break. People talk about the developing world as if the rich have all the liberty (freedom from prosection for example), but in reality everyday people with small sums of money can do much more of what they want. Parks are full of dangerous swings, you can buy food that might be on the turn, you can cross roads in dangerous places. And yes people get hurt etc. and there's no safety net. but the things that kill most of us are not these things. It's depression, lack of friends (they've done studies) work stress, or self handicapping behaviour. 

Freedom from destroying ourselves would be a difficult one to get on the statute books..
