To make something a "Right" is to make it the responsibility of everyone to uphold for you. You can't be guaranteed something without the compliance of the community.
For the right to free speech, and right to bear arms, this is easy. All it demands from everyone else is that they not legislatively restrict your speech, or take away your legally obtained arms.
Food is a different story. It requires others to put in actual work to provide you food. Your right to food then turns into the compulsion of others to work for no personal gain for your benefit.

Why shouldn't basic survival be tied with work that provides value to society? Before civilization, everyone had to hunt and gather for their own food. There was no divine right to eat without earning it.
