Let’s take them all, while we’re at it, shall we?
“No gods before me” - Not represented by atheists. If you take it to mean “no gods before God” then not represented by anyone except Christians. If you include that to mean any god, then not represented by polytheists.
“No worshipping of idols/graven images” - represented by some Christians, likewise some Jews, also some Muslims, I believe. But not really anyone else.
“No taking the Lord’s name in vain” - only Christians.
“Keep the Sabbath Holy” - I would say depending on your definition we can’t include even Christians in this one. Orthodox Jews would be included. No one else.
“Honour your parents” - This would seem universal, but what does it mean? Honour them no matter what they do?
“No killing/murdering” - The first of our universal ones, and the first enshrined in law. But even this is subject to interpretation. There are Christians who gossip, against your own interpretation. There are Christians in the military. Plus there’s the debates around abortion and euthanasia, which by the very nature of their existence show that there is not concondance.
“No adultery” - Yep, this is a pretty universal one. Oh, except for people who have more than one husband/wife/partner. Or for people who think it’s ok if you’re seperated but not divorced.
“No stealing” - The second one in law. Probably actually the most universal, really. Some people consider taxes stealing, but i’d still say this is the one you should hang your hat on.
“No bearing of false witness” - The last of the ones in law. Yep, in a good many places, thought of to be bad. Then again, some people would stand by the idea of white lies.
“No coveting your neighbour’s stuff/wife” - You use envy as your example, and i’ll agree it’s a pretty good one. Most people would say horrible envy is a bad thing. But not all envy - wanting things drives the world round, after all.
So overall that’s three in law, and five of them are *debatably * universal. At least four are definetly not universal. That’s really not all that impressive. Certainly not “represented in all of mankind”. So you are incorrect here.
Then it’s not easy, is it? If you have to overcome your own nature to see it, then it’s pretty difficult. Easiness can only be defined by the success rate and ability of people to get to it. If people don’t, then even if it’s a fault of their own abilities we must conclude it’s not easy.
