The problem is that property laws are local or national, because it's assumed that I need physical access to your property to do anything. If I fire a rocket at your property from some other country, I would be violating all kinds of air space regulations or maybe even international treaties on weapons.

We now have a better understanding of the unintended, global consequences of small, national actions.

Then it seems like the real need is for a better international enforcement mechanism. As cancerous as it is, maybe international copyright law could be an inspiration? I'm just highly skeptical of creating a whole new category of offense when our existing legal framework should already have ways of dealing with this kind of externality
