Those not allegiant to the beast won't take the mark & therefore be unable to participate in regular commerce, relying on a black market to survive.
Things like the mark of the beast and the seal of God are spiritual in nature and reflect whether someone is loyal to the dragon (Satan) and the beast or to God/Christ. One's spiritual loyalty has nothing to do with what type of currency they use (or don't use).
Not being able to buy or sell without the mark of the beast has to do with not being able to freely preach what you believe without being against Christ and loyal to Satan instead.
I already showed you that buying and selling doesn't have to relate to the buying and selling of merchandise, but you don't want to even consider that.
Proverbs 23:23 Buy the truth and do not sell it—wisdom, instruction and insight as well.

We don't know how far tech will have advanced by the time the beast comes. Big Bro may have a lot more capability by then.
Loyalty to either Satan and the world or to God has nothing to do with advanced technology. It has to do with what is in people's hearts and what they do. The mark of the beast is said to either be in the forehead or the right hand because it relates to people's thoughts and beliefs (forehead) and their actions (right hand).
No, he wasn't. Daniel, Paul, and Rev all refer to a MAN. And he will be in power when Jesus returns, as Rev. 19 proves.
Tell me how this man "WAS" before John wrote the book of Revelation then.
Revelation 17:8
The beast, which you saw, once was, now is not, and yet will come up out of the Abyss and go to its destruction. The inhabitants of the earth whose names have not been written in the book of life from the creation of the world will be astonished when they see the beast, because
it once was, now is not, and yet will come.
