That's plain invalid; you can't jump from 0d to 1d. Obviously.
You deny that a set is the union of its singleton elements? In other words if I have the set {a,b,c} I can write it as {a} union {b} union {c}. The same goes for infinite sets. You are free to deny that but then you'd have to throw out all of elementary set theory and all of modern math and physical science that's built on top of it.
Err no, I denied that the line is a set of 0d points.

Ehh.. Zero times anything is still zero, and the length of the unit is 1. However you simply can't create a 1-dimensional mathematical object from adding 0-dimensional mathematical objects.
The saying that a line is 'composed' of points only means that wherever you look on the line, you can assign a number to it. It doesn't mean that it's literally composed of 0d points.
Actually that's exactly what it does mean. You can express the unit interval [0,1] as the mathematical union of all its singleton points.

What is a line then?
What do you mean? A line is a continuous conceptual 1-dimensional object.

Take it up with Euclid. Or any modern mathematician. I can't argue this point with you. Did you miss high school math? The real line is composed of an infinite set of 0-dimensional points. You can make up your own math but you'll be denying all of modern math and science.

You really didn't figure out yet that this is a thousands of years old fallacy?

Ok so you agree that you are parting ways with the last several thousand years of human progress in math and science. That's cool. Can't argue with you.

Actually, nothing in actual science rests on this fallacy, in case you haven't figured that out either.
