You can make home brew easily enough with water, yeast and sugar. Stocks of alcohol does not seem like a good thing to tie money up in, neither does silver and gold.

Some ability to grow your own food, feed a goat and some chickens makes more sense for a longer term social breakdown if you are way out in the boonies. Being IN a major metro area...it just ain't going to be pretty if it happens. Mayhem will be breeding like rabbits.

Shelter, food, water and fuel is what you will need if the entire society is trashed.

I know a "Prepper" who had it all...for about 10 years worth...house burned to the ground. Got 120K for a 150K house and 60K in contents on probably $250K of contents with all his prepper gear. He now lives in a 3 bedroom townhouse with a water filtration straw. Being able to get away from people and live off the land is about the best long term solution, if there really is one.
