I feel like the answer to your question rests within the fact that the Ten Commandments, supposedly written as you say, "by gods finger" say nothing at all extraordinary. There is nothing special about them.
The first four are specifically religously concerned, and none of the laws were unique because many cultures long before God wrote these oh so wise words had laws just like them, one of which was Egypt, the land from which they allegedly had just come. The one time God actually writes something himself and all he manages to do is copy off of humans? Not very impressive for an all wise and all powerful deity.
Further, if you would be willing to submit yourself to such an archaic and barbaric standard then you would have to be willing to accept the consequences of violating it. Thus I expect it wouldn't be long before you were stoned to death, unless of course you wished to ignore that unpleasant part. But then you wouldn't be truly living by the standard would you?
