When it comes to Consumer Rights Acts which State's laws does eBay's policy reflect? The seller's State, the buyer's State or eBay's State? And if it's eBay's State what is eBay's State?
And, did we, as members, sellers or buyers, relinguish any of our Rights to file a civil suit against a buyer or seller?
< which State's laws does eBay's policy reflect? >
I'm not an attorney, not even close, all I can offer is my own opinion. I would say California. Even though eBay reaches internationally, they cannot comply with the laws of every state and every country imaginable.
They do try, though; they prohibit their members to sell certain items to certain countries; for example, you can buy pornography in the US and Canada but nowhere else.
Another example is firearm magazines. eBay prohibits the sale of magazines with a larger capacity than ten cartridges. Because some states have that prohibition, eBay applies it to everyone, even states that do not have that silly prohibition.

Again stressing that I'm a layman, I would say no. The User Agreement is between you and eBay.
Your Inquiry should best be directed to ebay for a response to the question presented related to consumer rights and ebay policy.
With respect to your second question please identify how and where you suspect you may have relinguished a specific right to file a civil action against either a buyer or seller
I'm not an attorney ... but I've seen it posted on these Boards that Small Claims suits between an eBay buyer and seller must be filed in the jurisdiction where the item was sold: the seller's location.
[You've already been told correctly that suits/disputes against eBay are handled through arbitration.]
