No you aren't. What you offer is no different in kind than what others in past times have offered in support of their belief that "now" was the time (1532, or 1847, or 1975).
That is because there were only two.
I disagree with you bob. In all those time you mention there was not the ability to put something on everyones hand or forehead without which they could not buy or sell. Well, 1975 comes the closest to that possibility, but even then the problem is that there actually WASN'T a marketable technology out and about with which to do so.
Whereas, I what I am offering is that today we actually HAVE the technology, cash, cheques and coins are slowely being fazed out, more emphasis is being put on other forms of monetary transactions that don't use cash, to the point that even in clubs in Europe people are having microchips implanted in their arm. You see, what is happening today is MANY more times relevant and applicable to the prophecy than those dates you mention.
Also, (I don't know who preached what around those dates), but invariably EVER theory I have heard from others who said that the mark has come, never seem to have the two basic facts of the prophecy backing up their claim. 1: no one can buy or sell without it, and, 2: it is in the hand or forehead.
I am also offering a very cohesive relation to what Jesus taught about not working for money and it's relation to the Mark of the Beast. Most, if not all of these other theories tend to consistently leave out any relevance to Jesus and his teachings. If the prophecy's interpretation isn't stemming from or leading back to Christ, then you can have a fair bet it's way off.
Therefore I am offering
coincidence (as in people already getting a 'mark' in their body, albeit in the arm at present),
cicumstances, (we ARE moving towards a cashless society, we DO have the ability to 'mark' everyone and make it the only way for financial transactions),
Jesus' teaching, in that his teachings of not working for money and living by faith are incredibly relevant to the mark of the beast prophecy.
With regards to your comment about the commandments, Jesus taught his disciples to DO and NOT DO a lot of things, quite aside from the 2 Greatest commandments. A command is a directive to do or not do something. A fun thing to do is read through the gospels, underlining every time you see Jesus telling his disciples to do something or not do something. You'll be surprised with how MANY things he expects us to do and not do.
