You did not ask me, but I feel compelled to answer.

Roads: Irreverent. Fuel Tax, local extortion taxes pay for these things.
Electric Grid:  Irreverent. Electric grid is payed for and maintained by people who buy electricity.
US army: NO. The military in it's current state is currently creating a tangible threat to the US through current actions around the globe that protect corporate interests, not those of US citizens.
Social Security: NO.  Is payed for through your voluntary contribution into the SS system. I have never paid a dime into it therefor I am not eligible.
