I am under no impression that there is homogeneous agreement among us in abstract terms. As a species we differ widely in our abstract framing of reality. There are many narratives, but as far as I can tell their common property is that they attempt to pull the message (the subject) from reality (the object) The localized "subject" we derive from objective reality varies considerably from culture to culture and person to person, but the "objective frame" we all derive that variable abstract framing from does have some global properties that apply to all of us as far as I can tell. These common ground messages are what all the variation comes from the same way all written words, that also can vary infinitely, come from a narrow set of symbols.
For instance, reality demands a certain level of commitment to specific activities in order to sustain us as coherent entities. Things like; stay away from cliffs unless you want to suffer the gravity of the situation, breathe appropriately to the situation - make sure to produce and distribute a sufficient amount of food to stay nourished as a community and or gather enough to stay nourished as an individual - care for the young and teach them to cultivate the nourishing opportunities as well as navigate and or contend with the hazards that reality presents or die out. In other words; we are governed by a common reality that requires we either negotiate the context of nourishing and antagonistic elements to remain coherent, or we suffer the consequences. We must pay homage to that reality if we want to derive a satisfying experience from it, our nature is reflective of its nature. We are a voice in the choir so to speak. Our shared experience is that we are children of nature, and it clearly states that if we sacrifice appropriately, and cultivate sufficiently, we can produce fruitful results that pay far more dividends when compared to the sacrifices they cost.
Reality conveys that we can count the seeds in an apple, but counting the apples in a seed is not as clear or easy when those seeds are cultivated properly. With this in mind, I do think there are abstract realities within our shared field of vision that are closer to our common source - that common source being what is conveyed through objective reality. We can embrace these realities, and leverage the opportunities available to us, or we can reject or ignore them, but the result in that case is we twist in the capricious winds of circumstance without a rudder or sail.
Assuming you believe the Bible is the standard for truth; it might be helpful to put what I am saying in Biblical terms; Psalm 19 says;
The heavens declare the glory of God;
the skies proclaim the work of his hands.
Day after day they pour forth speech;
night after night they reveal knowledge.
They have no speech, they use no words;
no sound is heard from them.
Yet their voice goes out into all the earth,
their words to the ends of the world. (NIV)
If we translate the common scripture that is communicated through reality into words more pragmatically: We live in an “almighty” reality that both created and conditionally nurtures us - that sets forth requirements (commands) that must be met for us to minimally survive and or flourish depending on how obedient and committed we are to the proposed relationship between us and that greater power - a greater power that acts consistently and faithfully in context. These grander global narratives we all share commingle with the more localized aspects of stories are often caught in word form. “don't eat pigs in a desert because they compete for the same food you do.” or “Don't kill the cows or you will have nothing to plow the fields next year”. The grander narratives globally shared are mingled with the more localized aspects of stories and we then see things like this woven into the fabric of the stories in the Bible, the Bhagavad Gita, Quran and the Tao Te Ching for instance. These writings capture what we need (or once needed) to know in a story matrix, along with many other things of greater or lessor use. As far as I can tell, there is variation, but there is also theme. There is our local abstract lens through which we frame reality, but we also share that common theme spoken through that reality as well. It is what we relate to and the nature of that relationship defines our experience of life. This common womb we share is our common ground as far as I can tell.
As far as I can tell, we humans have a real penchant to confuse the map with the territory, our words with reality, either by ignorance, or by those who exploit this weakness as a tool to leverage their social position etc. My guess is the morals thing we obsess over is the supposition that these things are necessary navigation aids that assisted us in remaining coherent at least at some point in time. They are like the froth on the surface of a deeper need to connect abstractly with the concrete, which is paradoxically fluid.
With all this in mind, I think your perspective that we are better off being committed to do of believe things than being forced to do or believe them seems appropriate to me. I do believe we have a common frame to establish things, but I also think some of us are lost in our own little words.
