If you can find even a single agency on that list which performs a function you wouldn't be willing to pay for, the rest of my comment follows for you, specifically: that agency is a net cost to you comprising both the taxes you pay to fund it (proportionately) and the decrease in wealth caused by keeping those people from contributing to the economy by doing something productive. This isn't specific to the US government, of course; that's just the easiest example.
Not beneficial to me personally does not mean "people ... who don't actually contribute anything to society on net", and it would take more research than I have time for to completely dismiss any US federal agency (except perhaps the DOD).
