great concept and I like the term relationalism you are coining here!
I do believe that an approach like this can succeed from the bottom up, eroding socioeconomic structures under the governmental umbrella by replacing the individual's focus on profit and lawfulness with a focus on human relationships.
Where other anarchist Utopias fail to convince (me), as they seem impossible to achieve without undergoing a destructive process to dissolve the state, this appears to be achievable... and maybe the process has already started!
