None of this sounds to me like anything American conservatives favor. As in, there is no legislation that's been championed by major Republican leaders that would do any of these things and, in general, none of these measures comports with conservative aversion to government spending and regulation.Here's where I think we are. There are several conservative policy wonks who are basically sincere, as far as I can tell, in their views on health care reform. Fragments of their claims and arguments are used, sometimes, by Republican politicians. The latter are basically uninterested in the substance of the issue at all. To some extent that's not unusual; lots of politicians talk about issues about which they have no real substantive interest! Some of it, however, is our old friend the post-policy GOP -- they really just aren't interested in policy at all, and therefore aren't constrained in their choice of talking points by anything policy-related.
In other words, the real-life Republican alternative to the ACA remains "nothing." But that's considered politically inappropriate, and so real-life Republicans get to hand-wave around the issue by identifying various things they theoretically would build a replacement around. However, for Republican politicians and many of the non-wonk other party actors (and perhaps some of the wonks, too), it really is just hand-waving. There's nothing substantive about it for them.
Again: that's not true for many conservative wonks. But politicians aren't using their work to build an alternative; they're using it for an easy way of having something to say that sounds sufficiently serious. And, again, while that's not unusual in any party on any issue at any time, it's unusually try for this particular party, on a very wide range of policy areas, at this particular time.
Also: nice catch!
