Lets say you take the country of Saint Lucia- Could they not spur the economy (among the lowest in the world by GDP) by saying any company can manufacture any existing drug and sell it? I feel like the medical tourism for that could be extreme, especially since there is still many treatments india still does respect the patent for.
If the country put it in their constitution that all drugs should be a human right, could a legal action be taken against the country itself? I imagine the only recourse would be the pharma companies trying to force legislation in other countries to bring sanctions, but I think that would be a hard sell.
