At 50% size, it looks excellent; at 100%, sharpening artifacts are visible,
it calls for a 2x resize.

Thanks, resize by 2 times in which direction?

Down, to about 1800 in length, or thereabouts.

But what's the point of such resizing? I'm not quite getting it, could you please explain? I've heard something similar, but didn't grasp the logic. I resized by 50%. In the output, I didn't notice anything except low resolution. Here, it's practically native resolution. Just a 10% upscale to reach 300dpi for printing on A4 (I want to try printing it).

In this case, the discussion is specifically for viewing on a monitor at "pixel-perfect" scale, i.e., at 100% zoom. Many viewers set the zoom to exactly 100% or use it as the maximum, so to speak, the native resolution. Hence the logic: the best image should be viewed at this scale, or at least the image should not show visible processing artifacts. Printing is a completely different story; it all depends individually on the equipment. Ultimately, of course, the choice is up to the author.
