It's ironic that you complain about the military while using the internet; which is based on the work done by the US military when it developed ARPANET sixty years ago.
And the web was invented by civilians working on basic science research.
Food preservation
People have been working on food preservation for millennia. Refrigeration via artificial means (i.e. not using natural ice) was invented by civilians (one cycle even invented by Einstein). Freeze drying apparently is very old, since you can do it in very cold climates using the weather. Modern freeze drying was invented by a civilian but it a heavily adopted by the military from near obscurity.
GPS: sure.
Radar: sure, the military put a lot of work in, but it didn't start there.
Nylon: nothing to do with the military
Epipens: autoinjectors or adrenaline? Autoinjectors predate military use and while they were basically the first major adopter, those ones are nothing like epipens.
And highways? You know who ELSE liked highways :) The modern highway (special intersections, separated carriageways, type restrictions) was a creation of the for the greater glory of the as something of a propaganda/self aggrandizement tool. For it to work well the dictator pushed for a "people's car", or in German, Volkswagen.
Superglue... kinda, but only kinda.
And duct tape, sure, but a lot of the heavy lifting, like pressure sensitive adhesives and tearable cloth tape was done in the civilian world. But that specific formulation with the plastic coating? OK sure.
Most of these things were initially developed without military funding. In some cases, like RADAR and GPS, the funding advanced them hugely in a short time. And in some cases it was the initial impetus for building them in America (interstates). Though in most cases this is a deeply inefficient way to go about it.
