> But there's a reason why most places discourage this sort of freewheeling exploration; when you visit a place and disrespect its boundaries, you often end up damaging it for the people who come after you. We're talking about abandoned buildings here. They are already practically ruins; I don't see how this applies. Even in your public parks example, we develop natural spaces so people can enjoy them even though doing so requires clearing some portion of the land for roads and facilities. Overall I agree that trespassing is selfish but I don't see anything wrong with that if it doesn't harm anyone else.
