Invisible Fence is a fantastic product that gives great value to many people. Seems to me that this could be the same. Note that Invisible Fence offers expertise in install, dog training, etc, over and above the DIY kits.

We recently put a deer fence around about a half acre and it was not inexpensive.

Another upside is that this would be reconfigurable. And there'd be a ton of ML-extractable insights for customer and the company.

PS: Skimming, I originally read the intent as "a fence to keep drones out", which is funny.
