I believe in people's right to do whatever, right up until people prove they aren't responsible enough for that. Our laws are littered with examples of this. For instance; most cities won't allow the keeping of personal livestock on less than a 1/2 acre of grazing area, if they allow it at all. It was not always that way. The deciding issue in these cases is almost always the ability to show harm.
In short, humans can ruin just about anything for everyone else. It does indeed irk me.
