"My personal opinion is it can't happen until there is no more paper money,ect...Seems a logical first step.."
That's the point of this...no currency required
If we are seeing the groundwork laid so that a literal interpretation of the Book of Revelation could be fulfilled, then there will be no stopping it, for as God speaks - so it shall be.
If we are not seeing that, or if the Book is to taken 'symbolically', then it doesn't matter as 'symbolically' all the events in Revelation are already happening on a daily basis. So life as we know it will not change.
In either case our work is clear. Preach the Gospel to the ends of the earth, make disciples of all men and Baptize them into Christ, and continue to allow Christ, who dwells in us, to shape us into His image.
