Well, if living in the 18th Century works for you, I won't gainsay your decisions.
I like things like electricity, computers (what are you posting with?), refrigeration, air conditioning, automobiles, airplanes,etc.
If all these things disappear in 21 days the I guess we will be back to the 18th century and, until you get overrun, you will be in pretty good shape.
If anyone truly thinks that scenario will play out worldwide, I congratulate you on your ability to play role playing games.
I would have done well in the 18th century, but I, like you, like electricity, so I can make it, from scratch, down to mining copper ores and smelting them. Refrigeration isn't that hard either. Real men today are responsible for creating stuff like that. And study to know how to do it.
Feeling so inadequate that you had to come on a 'survivalist' thread to belittle folks that have skills? And then threaten to over-run them with mutant-biker-zombies?
Give me a break and sniff the manure you are shovelling.
