based on the imminent collapse of the economy due to European influences and the carbon tax, peak oil, peak food, apophus, mass emigration and Shaira law, I think I would buy lots of ammo, a bunker, food and the supplies, some key medicines, water purifiers and a few other essentials that I could trade.
Here is an additional hypothesis , what would the most important and valuable items be in a post apocalyptic world - economic collapse followed by societal collapse. Items that you could trade, can get relatively cheaply now but would be of huge value once al supply chains have broken down.
