I think that the existence you described must be build on the harmony and balance between the individuals. In our true forms, which for me is the inner world, the energy of thoughts, the soul if you please, we can exist with others uninhibited and free. But due to the fact that we are bound by flesh, and the desires of flesh overshadow our true selves and cause all kinds of conflicts between the individuals, so that we cannot achieve this harmony. Perhaps, it's something to strive for as humanity, erasing the boundaries between the flesh and soul, cultivating the soul as it is more powerful than flesh, which is merely a vessel. Currently, everyone is obsessed with the flesh, as it is easier to please and thus easier to think that happiness can be achieved. Sex, drugs, wealth, food are all to feed the flesh but the soul needs totally different "food." The happiness of flesh is just an illusion. To cultivate a strong soul requires much more effort, on the other hand. I think that it's something universally accepted by all world religions, however every one has its own way of describing the path towards it.
Trust can be established when there's no fear that someone else could hurt. People hurt each other because of the lack of understanding and innate egotistic tendencies, once again fueled by the desires of flesh. If humanity could communicate by the shared thinking, like noosphere, discover this beehive of thoughts we could achieve the understanding of each other. Otherwise we are like echos bouncing off each other but never reaching all the corners.
The legacy of flesh is animalistic, which was required for our survival but overtime it will become more rudimentary as we move from the animalistic realm. We are becoming gods. Unless if we exterminate each other before that even happens, which is very likely. Man, it's a long process to get there
Realistically, ultimate freedom and trust seem to be metaphysical, the higher ground so far we couldn't achieve. Sartre would say that we are all free, don't know what to do with this freedom and thus plagued by the existential angst. My philosophy professor used to say that free will doesn't exist however there's cheap will, haha.
Interesting topic, I will be looking forward to see what others have to share about it
