You're perhaps confusing polyamory with polygamy/polyandry? To put it in hacker terms, polygamy / polyandry is forcing an edge reduction creating a hub and spoke architecture when the arrangement has to be a 1 to n-1 mesh. The equality of a mesh is an easy mathematical argument to make, but it isn't the argument polygamy/polyandry is making. Polygamy/polyandry is inherently unequal. [edit] to get the math right a polygamous/polyandrous relationship maxes out at n-1 contracts. Polyamory would be (n*(n-1))/2 contracts and I would argue for equality that if n changed all contracts would have to be retermed. Polygamy / polyandry is unequal. Period. It's a mathematical fact. Polyamory I could be convinced of the possibility of legal equality, but not for polygamy/polyandry.
