When the Mark of the Beast comes you can not engage in commerce without taking the mark, you can not buy or sell which also means you can not sell your labor, whether skilled or unskilled, to any potential employer. You will be out of a job when the Mark of the Beast comes, if you choose to reject it. So how will you survive without a job? You have two options.

1. Piracy/Stealing
2. Homesteading/Self-Sufficiency

These are your only two options. But the worst part is the world government will start persecuting those who do not receive the mark of the beast. Which means your piracy and/or homesteading operation must be kept a secret, underground. I think the best thing to do in the mark of the beast scenario is to form underground communities where people oppose and continually raid(piracy) the Mark of the Beast system. Perhaps the community can be hidden in a remote location unknown to the world government, or perhaps it can literally be underground, I think our best option would be to use certain cave systems to hide it.
