I've long believed that one should purchase anything gun-related as anonymously as possible, and prepping gear seems to have gradually shifted into that same parameter. But, what about food? You don't need to buy your food anonymously, do you?
With the incoming famine ("global food shortage"), I'm convinced that if you are going to purchase "larger" quantities of food, survival food buckets, or groupings of food that are commonly associated with prepping (e.g., 20 pounds of rice, 30 pounds of beans, and 10 pounds of dehydrated milk powder – nobody buys all that but preppers), that it is worthwhile to consider making an anonymous purchase.
Consider that it was just in 2020 that the FBI raided and stole a "hoard" of masks from a private individual who had purchased everything he owned lawfully. Consider that the Defense Production Act not only states that badges have the "right" to steal what you've "hoarded," but that they'll slap you upside the head with a felony for "hoarding" to boot.
It doesn't matter if you purchased all of that food lawfully. Under the DPA, you're screwed. Even if the food is from your own garden and you've canned it all yourself, the DPA could be used to steal all of what you've grown and canned for the good of the collective.
(If you remember A Bug's Life, this is the grasshoppers enjoying the summer and then robbing the ants so that they can survive the winter.)
