The reason I personally choose raw land over anything else is that it is a hard, tangible asset, not a piece of paper.
If you own a hundred acres, you can hunt it, use it for agriculture (crops/cattle/orchard), lease it for agriculture, lease minerals, live on it, have a nice weekend place etc etc. If the shit hit's the fan, you can just flat out move there and support life for you/family with the land.
Owning gold does not give you any of the benefits that land does, other than a store of wealth in a hard asset. Gold is nothing more than a hard currency, and if the shit hit the fan, I would not take gold from someone to give them food in return. The food would be more valuable to me.
But land is a store of wealth like no other, no matter what happens in the paper wealth world we live in, the dirt will always be there.
Just one piece I randomly found, very affordable and with minerals!
