Can you guarantee that water will not be used to drown people? Since you can't, shall we ban water?

We cannot guarantee that nostr will be used only for good things. Nevertheless, nostr is a public good.

I agree that exposing where Elon's jet is, in a "stochastic terrorism" kind of way, might help enable someone who wants to harm him or his family. But it isn't directly harming him or his family. The actual harming is where we draw the line -- harming someone is illegal.

When you flip it over and ask "should it be illegal to mention somebody's whereabouts" the answer is obviously no.

We live in a world full of risks. We cannot eliminate them. And we have to draw sensible bounds on what behavior is and isn't legal. AFAIK tracking Elon's jet is legal.
