> Given all that, talking about proportional representation is a complete waste of time, and it gets in the way of having constructive conversation about this subject. It is constitutionally impossible to disband the House of Representatives and switch to proportional representation
You are confusing "proportional representation" (an outcome which many systems approach) with Party List Proportional (an election method which is designed to achieve proportional representation.)
There is no Constitutional barrier to many PR systems (e.g., STV in multimember districts) in the US, though there are some structural limits to the degree of proportionality that could be achieved (you'd still have to apportion by population and have each state as a separate pool.)
There are some federal statutory limits mandating single-member districts, but those are much easier to reform than Constitutional barriers.
> Every time I see a thread here I really do look forward to reading thoughts that are actually about gerrymandering and solving gerrymandering
Distortions of the kind labelled gerrymandering are fundamental to the exclusive use of independent single member districts (and exacerbated if you use plurality or majority-runoff elections in those districts.)
This is an inescapable fact. You can't complain that you want to hear solutions to gerrymandering and simultaneously exclude all the things that actually address gerrymandering from the acceptable solution space. Well, you can, but you are making irreconcilably conflicting demands when you do so.

Not so much. In Australia we have single member districts but not really gerrymandering because our districts are set by an independent non-political body using an algorithm and some common sense. Look at an electoral map of Australia and you'll see that our electorates are reasonably sensible shapes, they haven't been set up to favour one party over another.

Heh, yeah...we used to have those in the US, too. Is there anything in AUS law that prevents infiltration by members more political than the body's charter anticipated?
There's always gerrymandering as a concept: If you build everything by algorithm, you are making the problem far smaller, but ultimately the decision of which algorithm to use is never going to be as good as proportional representation. Whether one only looks at population density and geography, or one adds ethnicities or party affiliations, there is no such thing as an objective algorithm that will not lead to biased results. The results will be more fair under any definition than the gerrymandering in, say, North Carolina, but they are still not going to be wonderful.
Given how the US political landscape is, it's not difficult to build a generic system that produces results that will favor the same party in all states. Compactness will, in general, be closer to favoring Republicans, while something that aimed for even population density in each district would favor democrats.
If I had to choose between any algorithm and what we have now, I'd pick the algorithm, but it's still going to be a worse output than someone actively redistricting aiming for maximally competitive elections or a proportional system.
