The fellow writing the article is not well grounded in knowing where to store food. In two places he suggests storing food in a garage. Here are his words about garages:
For those (more fortunate) individuals able to devote entire rooms (or perhaps a garage) to such investing;...
For homeowners, who have considerable living space, but (for whatever reason) have little storage space available for food investing; building a structure for food storage, such as a shed or (expanded) garage is a cost outlay which would likely pay for itself over a relatively short-term period.
A shed or garage will have high temperatures and that causes food to spoil rapidly, even twenty year food deteriorates at a rapid pace. Cool/cold temperature is required for maintaining the shelf life of any food. Plus, varmints (think rats, raccoons, squirrels, etc.) will get into stored food if left where they can get to it. Many people leave their garage doors open and that is a feast for varmints. Never store food in a garage or other outside location. This guys food is going to be spoiled or eaten by varmints.
I recall reading about Mormons who are required to store food. The church had to counsel their members because members were using their garages to store their food.
Store food in the coolest place you can manage. Heat is a destroyer of food.
I’m done giving a few cans to my neighbor who refuses to listen and stores food in a H-O-T Texas garage.

Same goes for water.
There’s a reason our grandparents had root cellars.
