What's gonna happen when the redneck militias start building these on their compounds? I'm terrified of domestic implications - police departments can't go buy old military gear to squash these yet.
At some point we just have to accept that we live in a society that relies heavily on trust and care for each other.
I've thought about a parallel version of this since I was a child and learned about the existence of nuclear weapons being a 'nation state' level of difficulty. Over time I assume an individual will wield more destructive power. How long before any individual person can conjure up world-ending munitions?
The early Ukraine war FPV drones were armed with warheads from lightweight anti-tank weapons, like the RPG-7:

The newer drones may have dedicated warhead designs now, but the concept is similar. They carry high explosive warheads that aren't sold to civilians. It's the same reason the militias don't already have anti-tank weapons.
