If I ever get nostr famous and can stack a huge amount of sats from providing (arguable trash) value to many plebs, I'd put those sats to building and documenting a how-to of building your own anti-Killdozer rifle. I'm one of the few people who is capable of doing that, and once it is thoroughly documented, making your own anti-Killdozer rifle would be significantly easier for many.
I also know a little about designing EMP weapons. ZAP ME!
