If payment of taxes is necessary to use the land, the government really owns the land, and is granting you permission to use it. The permission can be revoked at any point. Payment of taxes greatly reduces the risk that the government takes the land you're living on, but does not eliminate the risk.

If you really want to "own" anything, at some point you must be prepared to deal with some other entity's claim to your possessions. Lenders, governments, and the desperate all may have claims to what you have.

Owning land legally in the eyes of the government means at least that taxes are paid. Where does the money come from to pay taxes? The only payment universally accepted for taxes will be legal tender, meaning that the land owner must have income dependent on the external broken system.

How can an individual or group be sustainable or self-sufficient when energy and resources represented as money continually flow out of the group as taxes?

If the answer is, you can't both be sustainable and pay taxes to an external entity, then to "own" land you must also be able to defend any forceful claims against it by the government. A perpetual state of low-level battle readiness may be necessary for this kind of sustainability. The upshot is that it will be much easer to defend claims by the government when it has its hands full with myriad other chaotic problems.

Kentucky Coffee Tree?

Chicory mixed with it and you could come close to cafe au lait.

What did I miss?

Frankly I prefer tea and it can be made from a variety of plants. I like sassafras tea in particular.

P.S.And to add to it I used to smoke grapevines. As well as rolled up cornsilk..but tobacco(burley) is easy to grow here. Some like to grow other varieties of smoking products and in fact pot is considered to be the second biggest cash crop here.

P.P.S.I did try some but I didn't inhale...cough cough.
