If you can stomach it, pemmican. It's got an insane shelf life (reports of it being good after 50 years buried in the ground).

You can get 2 lbs of it for $47.12: https://grasslandbeef.com/products/salt-free-pemmican-pail

At least according to explorer logs, 3/4 lb is enough for a man for 1 day, so that's about 2.75 day's worth.

Fun fact: the short stories that the series is based on is by my good friend Ken Liu (he wrote the foreword for Programming Bitcoin). There are also various Bitcoin references on the show, which I'm sure he had a hand in.

If you're serious about this, the two books that were recommended to me are "Buy then Build" and "HBS Guide to Buying a Small Business." I've read both and they're very good.

The main obstacle for me is that it takes about 12-18 months to find one that's actually profitable and reasonable to take over and in the right geography. Also, these days, you're competing with a lot of private equity firms who are bidding up anything that's actually profitable. Fiat money has found its way to even small businesses.

But yea, if you do pursue this, it's not a short process and you'll need a good accountant and lawyer at a minimum. All that said, I hope you find something profitable to do with your time.
