"Isn't it possible that it is designed to find out who are the Christians?"

I know that I mentioned this before, but is there a possibility that the buying and selling restrictions surrounding the mark of the beast, are not there to force people to worship the beast, but actually to try to expose those who won't?

Revelation 13:16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: 
  17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. 

Previously, it mentioned how nearly everyone is taken by the beast, and worship him freely:

Revelation 13:3 And I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast. 
  4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him? 
  8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. 

It says in line 13 that all the world wondered after the beast.
Then in line 4 it says that they worship the beast and the dragon, so wouldn't the "they" refer back to line 3, "all the world"?
Then doesn't line 8 clarify who does and who does not worship the beast?
So, why in line 16 & 17, would those who already worship the beast, need to be forced to take the mark?
Wouldn't they be more likely to receive the mark gladly, in their worship of the beast?
As for those whose names written in the book of life of the Lamb slain from the foundation of the earth, they don't take the mark.
The LORD knows which names are in the book, but the beast and the false prophet do not.
Then the false prophet makes it so no one can buy or sell without the mark.
So wouldn't this rather be a way to "smoke out" those whose names are written in the book, who do not worship the beast?
Wouldn't that buying or selling restriction quickly show who they are?
Then wouldn't they be taken, asked to denounce Jesus by taking the mark to worship the beast?
Then wouldn't they easily then know whose heads to cut off?

Isn't the mark far more about worship than it is about technology?
Every time chips are enhanced, people keep saying that we are getting closer to the mark of the beast.
However, does technology move people close to worshipping the beast, or is it a spiritual thing?
