No, it's not what most competitive players do.
Anyway, you all could keep going back and forth and not getting anything done, or take passive aggressive shots at one another all day, or you can attempt to come together. I know that's hard for you all, since you all basically hate each other or at the very least have a small amount of disdain.
Now lets look at what we got here.
Now, there are somethings each side is refusing to give up. One side will absolutely not agree to only have one item, and/or multiples of each item around. So take that off the table.
On the other hand, one side will absolutely not agree to defending items, or having such strict strip regulations were you may have to constantly prove your activity if you have a somewhat popular item.
Where does this leave us?
Well, many people protested having only one item, perhaps raise the number and discuss a # that suits both.
Or, I've seen many people on both sides clamor for a reduction. So perhaps open up all summons to being used, and have a discussion on what jutsu to take off the claimed list and leave only the highly abusable ones on there (Edo Tensei, Hiraishin, things of that nature).
Or perhaps these ideas of mine are rubbish, but start to bounce ideas off of each other, that's what these threads and forums are for. Think logically about both sides, before posting, try to be constructive. Don't get off topic, don't get into debates about ranked vs casual, or go into a profanity laced post about no one hearing you.
We're better than this. There is no reason to be hateful, spiteful, or generally rude. Start compromising, working together. Or just lock the thread and never avoid each other indefinitely.
