Starting from simple terms

It's not about the paper. It's about the community.

Title is ownership. Unclaimed land may be claimed in a reasonable manner. A claim, all by itself, is title. Unclaimed land remains unclaimed when a claim is unreasonable. A reasonable claim is one that can be defended by a community. Lawyers are not the arbitrators of reasonable. Force should not be the arbitrator of reasonable. This is why [local] community is important.

A deed is a conveyance of title (to buyer from seller, or a gift) and is often just for title to a part of something owned.

Neither a deed or a title is a piece of paper. Paper is just a convenient way of recording them.

A chain of title is used to confirm title. It is a record of title and deeds from the first claim.

Sovereignty has nothing to do with it other than most claims are originally made by sovereigns.

The OST prohibits sovereigns from making claims. We'll see how long that lasts.

Not keeping to simple terms just causes confusion. Some would attempt to destroy these simple truths...

Masson-Zwaan: 

I think the Outer Space Treaty should stay as it is. In my view it is a brilliant document. …there is a treaty signed by sovereign States [the OST] which prohibits appropriation by the state, and hence by its subjects, and that there is nothing they can do to argue around that.

We aren’t subjects in this country, lady! The part I put in bold is pure assertion. Why make it? Because they still hold that Socialist/Marxist dream of utopia and see the OST as its foundation. A dream that only brings poverty and death where ever it's tried.

We can only hope the prohibition of state claims can last long enough for private claims to take hold. It has a slim chance. That chance becomes much stronger if a community binds itself with a settlement charter.
