> We all have outlets, which limit the amount of power they will supply, and some even check to make sure it isn't supplied through us, or into a system that has arcing issues. Not that you don't have a point, but outlet safety measures only address accidental failures. A malicous device is perfectly capable of storing power in a battery or capacitor to exceed instantaneous power limits, or running at 12 amps (out of 15A fuses) 24/7 to pull much more power than you expect over time, or electrocuting you taser-style even if it doesn't have a high-current ground path. So while the safety features are useful, they're not particularly relevant to security. The wallet example is pretty good, though, as is your actual point.
