The fact that something isn’t a 3d object doesn’t mean it doesn’t exist. Does a line of contrast between 2 colors exist? Does a movie projected at a wall exist?
Comment on Do straight lines and flat planes exist in nature?

Lines and planes in the mathematical sense are 1 and 2 dimensional. They don’t have any height (and lines also no width). So they can’t exist as a physical object (made out of atoms) as they are already 3 dimensional.
They only exist as a concept.

Does a line of contrast between 2 colors exist?
I’d say no. And even if it did, those colours are made out of atoms or light, both of which are “fuzzy” and 3D and can’t make a proper line.
Does a movie projected at a wall exist?
Sure. There is photons bouncing of a wall and the information they carry we call “the movie”. I guess that counts. But the relevant bit is the wall and again it’s made out of atoms and there is not a proper flat 2D surface.

Then, o pedant, do straight or flat objects (thus linelike, planelike) exist?

Why ask a pedantic question and be upset by a pedantic answer?

Graphene is a great example of a planar molecule, within 1 atom of tolerance.

You could get serious Van der Waals off a couple sheets of that.

Their manifestation in our world was limited, they have already gone to another plane of existence
