If the SHTF scenario you paint arises, an ounce of lead will get the ex-Navy SEAL more bread than .1 oz of gold. :)
In a real SHTF scenario, the owner of a still, and the knowledge of how to operate it, which is able to turn any old fruit or food waste into barely passable vodka, is going to be the richest man around.
He will still need those SEALs, but they will be his security staff.
Not happening until the day the citizenry loses complete faith in government.
