Wow.  Ok, quick true story: internet was disrupted in part of my county recently as they were upgrading the new fiber ring, and a backhoe cut an existing main trunk.

All the electricity in the area worked fine.  Lights were on.  Cars were driving around.  I was walking into my bank when it happened.  I couldn't deposit my check because their systems were down.  My wife wanted me to pick up some grocery stuff while I was out.  The entire Walmart was a chaos because payment and checkout systems were down.  Lines of buggies but you couldn't pay.  Went to Kroger.  Same thing, but they had had time to close and put up a sign saying temporarily out - check back in a few hours.  Went to get gas.  1st station pump didn't work.  2nd station did work, but there was a sign saying cash only.

My point being that you may indeed "live" if the internet goes down, but almost ALL the systems that run all the banks, businesses ad stores around you will not.
