It seems like the crux of it more so is what the providers accept. If a major driving force is to improve administrative efficiency for providers (which it appears to be from reading this article), then it defeats the purpose if providers are still accepting payments from other insurers. But it seems like you could controller this at the provider rather than insurer level, that is by forcing providers to only take payments from the national plan. Then if any insurers were selling plans, they would be fraudulent because they couldn't actually pay for anything. But I can see that this is more or less equivalent to the law I was asking about, so I suppose I get it now.
