I'm with you on these thoughts that a better world wouldn't require us to ask for equality.
What you're talking about here a great deal is unity, which already takes care of "equality" where necessary or relevant.
This is why I bump heads with equality-hustlers all the time, because they bang on about equality as a political concept but give no thought to philosophical and scientific insights of unity. In fact, they're often anti-equality when it comes to people they disagree with or denounce for whatever reason.
Also, being battered over the head with propaganda and rhetoric about equality near-constantly has some unintended consequences. Not only does it bring our arbitrary, surface-level differences to the forefront of people's focus, essentially widening any perceived divide and making real unity that much more difficult achieve, but it also pushes people into seeing people in terms of group classifications.
This means individual people can have their originality and personal circumstances overlooked in favour of some standardised view of "the group" they belong to.
This is also why I appreciated you putting your focus on human beyond all else.
It's a nice thing for people to say - you hear it enough in conversation where people try to sound open-minded or something like that. But you quickly realise a lot of these people still think through the same divisive languages of thinking that keeps people divided up.
Keep up the writing, and the philosophising!
