There's no avoiding the point that there is no easy replacement for oil. There are hundreds of ideas that will work as one-off attempts to move one specialized vehicle over a known course. But what will and what won't work comes down to a matter of scale and economics. Everything that appears to have hope for the needed scale is more expensive than oil. Everything that appears to be cheaper than oil hasn't nearly the prospect for a fraction of the necessary scale required to replace oil. Whatever anyone hopes to use rather than oil is going to require changes on a scale one can hardly imagine. The smallest changes would be something like needing 6 times as many electrical generation plants as we currently have operating. The less practical ideas make Apollo moon programs look like someone's hobby during the summer vacation.

While I do agree with you, I have three points to offer-

The first space flight didn't reach the moon, and we haven't yet reached another planet, let alone another world. Yet space travel gave us the computer, modern communications, and many other technologies.

Until we develop energy alternatives, which will take time, we can't drive the Arabs back into the sand.

The road to discovery is paved with what didn't work, first.

One early example of getting this wrong is I G Farben, they believed peak oil had been reached in the late 1920s and invested heavily in synthetic oil production, the losses they were making on this when huge discoveries were made was one of the reasons they supported the Nazis, as the autarkic policies would restrict imports allowing I G Farben to make a profit. ...
