You are arguing over the losing side of a debate that was settled almost 50 years ago, when 40+ countries (and over 120 more that have joined them since then) got together and agreed that yes, healthcare is a human right (art. 9 and 12) and yes, you do also have the right to adequate food and housing (Art. 11).
Second-generation human rights do not work in the same way as First-generation human rights, in the sense that you can't force individuals (trough the government) to prevent them from infringing on your rights, but you can force the government (a public entity) to grant you such rights, by using people and public funding as means. Second-generation human rights are not enforceable against individuals, but against the government. To use one of your examples, you have the right to demand from the government doctors or medication at an adequate cost, that in turn, the government will get from pharmaceutical companies or the medical community with public funds (the details are left to each country to establish).
