Right, you would have some survivors, but people would not be concerned with paying taxes or anything related to tech/the internet.

Even rural areas would be very rough. Supply lines for gasoline would probably be disrupted so unless you can grow enough food for subsistence on your own land, local agriculture wouldn't help you much. We'd have to go back to horses and carriages, but with the exception of Amish areas, I doubt there are enough horses and related equipment around to make it work. And then there's security, which is probably the biggest issue. Even if you can sustain yourself, you'll need a way to deal with packs of hungry, desperate people going around with guns.
