There are two positions on whether or not something is finite: It's finite, or it's infinite. "It's complicated" doesn't exist on the spectrum.
You're arguing that a wider availability of healthcare has potential feedback effects. I don't disagree. What you fail to establish, however, is that healthcare is, in fact, an infinite resource. You make a strong argument that demand for healthcare is considerably more elastic than we might suppose; I don't disagree. You make a strong argument that wider availability of a drug results in more utility; I don't disagree. You make a strong argument that for many problems in the healthcare domain, wider availability of a cure is better even for those who would have it available anyways; again, I don't disagree.
What you fail to establish is that the resources to provide healthcare are, in fact, infinite, or simply non-finite. You discuss demand; you don't discuss supply. You discuss the utility of a bigger supply; you don't discuss the mechanics of actually increasing that supply.
I can confidently say that the world would be much better off if, all other things being equal, there were substantially more healthcare resources. In this, you and I don't disagree.
Where we may disagree is whether increasing those resources in a world in which all other things -won't be- equal is the best course of action.
Is blue "finite" or "infinite"?
If everything is either "finite" or "infinite" you should be able to answer the question.
In line with the results of the poll here, a thread for discussing politics. Incidentally, folks, I think downvoting the option you disagree with in a poll is generally considered poor form.
1.) Top-level comments should introduce arguments; responses should be responses to those arguments.
2.) Upvote and downvote based on whether or not you find an argument convincing in the context in which it was raised. This means if it's a good argument against the argument it is responding to, not whether or not there's a good/obvious counterargument to it; if you have a good counterargument, raise it. If it's a convincing argument, and the counterargument is also convincing, upvote both. If both arguments are unconvincing, downvote both.
3.) A single argument per comment would be ideal; as MixedNuts points out here, it's otherwise hard to distinguish between one good and one bad argument, which makes the upvoting/downvoting difficult to evaluate.
4.) In general try to avoid color politics; try to discuss political issues, rather than political parties, wherever possible.
If anybody thinks the rules should be dropped here, now that we're no longer conducting a test - I already dropped the upvoting/downvoting limits I tried, unsuccessfully, to put in - let me know. The first rule is the only one I think is strictly necessary.
Debiasing attempt: If you haven't yet read Politics is the Mindkiller, you should.
