Throughput does not directly equate economy. More roads leads to more scattered land use, and there is no 1:1 relation between land use patterns and economic productivity (additionally, there are many other aspects to this like qol and environmental concerns).

Well, yeah, what I said was a simplification and an assumption. Throughput doesn't directly equate to economy, but it's one of many tools that could be used of the goal is growing the economy and needs to be balanced against other factors. Maybe I should have elaborated more in my reply. My point was that I've heard that argument /a lot/ but I never hear alternatives or what I feel like is an honest discussion (maybe I'm just out of the loop). The scenario usually starts with, "a road is busy and citizens what something done about it." The obvious choice is to expand the road. This obvious response is, "that won't fix traffic." What I'm saying is there are other reasons to expand and I also haven't heard alternatives to expanding the road that are any more proven to work--which I'm genuinely curious about.

  The key is reframing 'mobility' as 'accessibility'. The fundamental 'solution' (although I dislike that word because it implies a global maximum) is different planning and incentivizing users of infrastructure to make choices that better align with the common good; put less nice, to force them to internalize their costs. There are two goals that are in direct conflict in your scenario: one is 'keeping voters happy', the other is 'make efficient use of infrastructure, and minimize externalities of transport' (this goes for other issues as transport, for example water management, but let's keep it concrete for now). The 'solution' in your example is simple, from an engineering point of view: toll roads, congestion charges, smaller and more dispersed schools and healthcare facilities, denser residential development in fewer urban centers (=less sprawl), and a bunch of other, smaller measures. Obviously this is impossible (no single administrative unit can do all or even several of those things), as well as too slow (we're talking 5-10 year implementation timelines, + another 5 or 10 for the effects to really set in). It's all about trade offs, and stopgap measures to keep things rolling in the mean time. I've been on all sides of this: informing the public about these things (haha good luck, even the 'average' citizen who has time to get involved in this is a raging lunatic, in my experience - let alone the real troublemakers), convincing policy makers to (also) look at the long term, infrastructure builders/maintainers who are essentially firefighting most of the time, ... One of my former colleagues wrote his PhD thesis on the effect of remote working on transport demand; if you're really interested, email me and I'll see if I have a pdf somewhere. (I've been working in this field for 15+ years, which is not to say that I know everything or even that that means that I'm right at all, but I've thought about this longer and harder and studied it more rigorously than 99.9999% of the population)
