The bulk of Moses' message, coming off 40 hungry days with The Lord, is: "Bring Me sacrifice. Lots and lots and
lots of lovely sacrifice. Build me a nifty house of expensive woods and fabrics, decorated with precious metals and stones, and burn me some virgin cattles." Which is a very odd thing to command a bunch of escaped slaves in the middle of a desert. Seems like God took a keen interest in lucre and the minutiae of tithing, even back then. Probably why he told them to steal all the Egyptians' gold and silver before taking off.
But, yes, it's in there. The succinct version is Exodus Ch 20. The two rules about worship take several verses to relate; the common laws are a single line each.

So keeping ALL the laws of God simply takes a few readings of the Bible in some reliable translation,
You left out the second half. "All the laws of God and man". If you think reconciling God's laws, then and now, here and there, is difficult, try reconciling them with the criminal code of Astana, the banking regulations of Oslo and the traffic rules of Cincinnati.
I make a clear harm exception for self defense and defense of nation. Those are the only 2 occasions that anyone should be killing anyone else. I'm fine with capital punishment for murders too, or any treasons that got someone killed.
Yup. You make exceptions that have potentially so wide an interpretation that you may as well scrub the forbidding in the first place. And that's just for homicide! Imagine all the
other harm you do, directly and indirectly. What rules apply?
Wouldn't it be easier to just behave sensibly?
