DARPA has advanced needs, which is why they develop advanced technology. Most people do not think of needing the things that the military needs, because most people's lives are not as challenging as a soldier's.
These policies are not a panacea, you need strong, accountable institutions for any of these things to be a benefit. Italy's hospitals have been over capacity for more than a week now, we will be soon, and so will the U.S.
Also, the U.S. defense establishment and industry is the source of many of the medical advancements you pay taxes for today, you don't live alone in the world. It is extremely childish to lash out, and call everyone a joke or a bully or an idiot, when these advancements are basically stagnant in your society, but people are willing to share them with you.
We're all in this together, whether you like it or not.
