Cars are just more convenient than trains for your average person.
On one hand, greater convenience...
On the other, the hypothetical end of the human race and/or modern civiliztion because of resource "scarcity."
Now before you freak out, yes I am overstating the case. However, the goal is is to
illustrate the nature of this discussion. On one side we have people saying that there are diminishing resources, overconsumption, that things cannot continue, that the population must be reduced...and generally claiming that there are some serious problems.
On the other side we have people saying that no...there's not really any huge problem here, because there's nothing going on that we can't solve. To which people in the first group are responding, "oh, no...we can't use those solutions because, woe is us, it would be
inconvenient to do so."
Like I said, it's a stupidity problem.
I'm not saying that trains are "the answer" to any specific problem being discussed. They're merely
one possible answer, out of many possible solutions. But there's a mindset here that needs to be overcome before any useful discussion can take place.
Look back at history. At one time there were people saying that horses would never be replaced and automobiles would never be anything but a toy for the rich. And that point of view might be easy to call silly now, but is it really so different? We didn't used to have paved roads. We didn't used to have inetrstate highways. Is it really so difficult to imagine someone thinking it ridiculous to expect cars to be common or useful because it would require building a massive network of hundreds of thousands of mils of roads and tens of thousands of miles of interstate highways?
And yet,
nevertheless we did it, and cars are useful, and so normal that some of you are having difficulty imagining life without them.
Again, I'm not saying we need to get rid of cars and start laying train tracks. That's totally not the point. The point is that
we can do things that we set our mind to.
We can change the nature of society even if the changes we want require massive modifications of infrastructure and way of life.
We can choose to do things differently, and there's no reason for that change to mean returning to the dark ages or living in huts wearing animal furs. It just doesn't need to be that way.
All of the "problems" claimed by the end-of-civilzation-due-to-scarcity crowd can be overcome. There's no "problem" here that we don't already know how to fix.

In vitro meat has been technologically viable for years. It's only expensive because there's no economic incentive to develop it commercially so there's no established induistry already able to benefit from economy of scale.
*
Atmospheric water generators are already commercially available. You can buy them right now for home use. They extract water directly from the air.
* There are countries already
producing 20% of their total electricity via wind generators. If you don't like wind there's
solar. If you don't like solar there's
geothermal. If you don't like geothermal there's
hydroelectric. If you don't want any of those in your back yard taking up space then build orbital satellites to collect solar from the sun and send it back to earth. Whatever. Take your pick. The point here is that there are options.
Lots of options.

Tokyo has a population density of 6000 people per square kilometer. The
US alone has 9.8 million square kilometers of available space. If you were to develop that space as densely as Tokyo, you'd have room for about 60 billion people. I've been to Tokyo. It's a nice place. It has parks and gardens and open space just like the US. It's no scary, dystopian hellhole of gridlocked skyscrapers like you may have been led to believe. If fact, it's not even one of the
top fifty densest places in the world, by a factor of at least 8.
* There are
synthetic oils,
biologically derived fuels, and
purely electrically powered cars. There is
no reason at all for us to be forever dependant on digging up crude oil, nor is it necessary for us to do without private vehicles.
Pick any problem you want from this discussion and
it already has solutions.
