>will be forbidden from buying or selling, from working, etc.
Nice try, but that wouldn't be what the script says.
The script says "no man might buy or sell, save he that had the mark", it doesn't say that it would just be forbidden, which means jack + shit when you can simply work for food, which would be selling your work force to get food - no money involved, which would violate that script.
This means the script was written by dumb fucks, who had no idea what they were doing, which also means at least these parts of the bible were written by the powers that be, who are pathetic pathological lying rats, which makes at least parts of the bible man written fiction.
All they could actually do is collapse their current money system and try it with another money system and control the dumb fucks who would go with digital shit coins. That's it. That's all that is actually possible in reality. And for these dumb fucks they could of course say that bank security requires an implant, but again everyone that says "fuck you" would be able to leave and they couldn't do shit about it. Too many leave and it's all over.
>you, you would lose your head
says who and what army?
Remember US military didn't stand a chance against people in Afghanistan, armed with just a few AKs. No military in the world would be able to do this. Anyone starts with this shit and the "just doing my job, which in this case is beheading people that don't want the new banking system"-Nazis would be dead. It's impossible to believe that you are the good guy in such a situation.
