@bgenlvtex T'was merely a joke; however, your closing statement (that there is no such thing as "nobody needs") is the statement that I believe is incorrect. Some things, truly nobody needs in order to overland (or travel in general). As I stated in the joke post, absolutely nobody needs personal private property in order to overland. Some (insert: the homeless) overland because they have no personal property. They own (or at least take with them) objects to facilitate survival and travel, but they own no property on which to build a home, or on which to store or work on a vehicle (or shopping cart).
To say that there is no such thing as "nobody needs" is as much a blanket statement as to say that "nobody needs" a given object. Thus, you are simultaneously correct, and incorrect.
The statement "Nobody needs" is an assertion that you (or anyone in this case) possesses the all encompassing knowledge and authority to determine the needs of all other people. I suppose it is possible a person could be so full of themselves that they actually believe that, but they would still be wrong. This was very clearly demonstrated in the last 3 years. Yes I'm tired and disgusted with petty tyrants casting their own self assigned authority to regulate the "needs " of others, very much so. In fact as you can see I've become absolutely intolerant of it.
You, I, nor anyone else possesses such all encompassing knowledge of other peoples needs that we can determine what "nobody needs". Offering an opinion on what someone else is likely to/ commonly/infrequently/occasionally/rarely need sure whatever.
Whatever, I don't know the guy who wrote the article and frankly based on that article have no interest in knowing him. The entire thing smacks of class envy and jealousy and is indicative of a personality that has been drinking way too much of their own brand of Kool-Aid.
If I was likely to be "overlanding" in/near/through Portland or Seattle or some other area with a large population of feral humans I very well might need some or all of the features found on the Mammoth ELE that the author of that article seems fixated on.
"Personal property" are your belonging(s) if you own the clothes on your back, or a well used McDonalds spork that you use to eat cat food in a dumpster, you own personal property.
Straight up, don't tell me what I need, I certainly won't tell you.
