I agree. Our laws currently are build around the assumption that there is exactly two people in a relationship. It would take a major overhaul of many laws to change it.
It has only worked in poly-one-sided kind of societies. You poly too much and you get communes, which get awfully hard to track lineage and other problems. In today's society the problem would be more along the line of financial, especially with both men and women able to earn their own way.
There are societies where poly works with out it being hierarchical, but those societies are
very different then ours, and would not be easy to adopt. I think that poly marriage is something that our society will have to address in the future, as our numbers are getting substantially larger, and I think we can find solutions. But for now, I think the poly community needs to let the national discussion remain on same-sex marriage, and only ask for decriminalization of multi-partner relationships.
But, OT...
I agree. This will be my last post on this subject here. If you would like to continue talking about it, create a new thread and we will pick it up there.
Object marriage is where you marry a non-human thing, such as your car or your dog. It is not allowed due to marriage being a legal contract and informed consent must be provided by all parties involved. A non-human (or a human below a legally determinated age of consent) cannot give this informed consent.
But at the same time we don't require a non-human object to give consent for anything else. The cow obviously didn't consent to being slaughtered for it's meat. So, the question is, IMHO, is two way consent something that is so inherent to marriage that to remove it would invalidate the concept.
