I'd guess that he opposes large-scale socialized medicine on these grounds, though that's not a foregone conclusion and I don't think I've seen an explicit statement from him about this.

I vaguely recall Robin noting that socialized medicine (as implemented in other countries) tends to reduce both supply of medical treatment and money spent on such, so I'd actually expect that he would weakly support it in the sense of "more optimal than the current system". I could be wrong, though.

However, I'm pretty sure he feels that other options would be superior.
