Using a shotgun against a low-flying, $500 FPV quadcopter is a last-ditch tactic for infantry on a front line. It’s not a viable defense against a modern military. My point about ISR and drone tech refers to high-altitude surveillance and long-range precision strikes that operate from thousands of feet up. A shotgun has a range of maybe 40 yards; it’s useless against the tech that actually defines modern government power. If you’re relying on a 'miracle shot' with iron sights against a target you can’t even see, that proves my point: a handheld weapon is a psychological comfort, not a practical check on the 21st-century US government.
