Military pilots are trained to fly in areas where electronic warfare is commonplace. That's not a risk that needs to be in my risk matrix as a GA pilot.
I personally think it takes a decent chunk of hubris to believe that the likely out-of-date chart that you haven't picked up and actually used in years is going to help you and not impact your airplane control while you find the correct chart and then fold it properly. If we're talking VFR sectionals, I'd need to carry four charts to cover my state -- three, just to cover the area in which I typically fly. Good ole Michigan -- we lost the sectional lottery.
I treat my electronics as required equipment, just like you would apparently treat your sectionals as required equipment. I check their battery level before every flight. If they aren't charged, I don't fly. If I don't have a way to charge them in flight, I don't fly (particularly if IMC is in any way a possibility). If one of them fails during a flight, I seriously consider whether it's safe to continue the flight as planned.
I see paper charts providing a tiny amount of risk mitigation, which is easily outmatched by treating the electronics as an important checklist item and making sure to carry enough redundancy for the mission.
You know who also doesn't carry paper charts anymore? Part 121 airlines. They take risk mitigation pretty seriously.
