If the point moves then it's coordinate has changed. You said there was no change in math, so the idea of a moving point makes no sense as a mathematical object. However, anything that changes can be viewed as something that is static with one more dimension added. So you can replace the notion of a point moving up and down a 1 dimensional line with a 2 dimensional static view tracing that motion over time. Could you not?
