That link doesn't claim that points don't exist in reality.

On the contrary, it is quite meaningful in the context I am applying it in. What day did he write about last year? This wouldn't even be a point in the sense of having no "thickness," it has a temporal "thickness" of 24 hours. Yesterday is a point in time in that sense, to say that yesterday is meaningless will not help matters.

It's perfectly relevant here. Was there something I did yesterday or not?

The point at which the future stops and the past repeats all over again. Again, it seems self-evident that yesterday happened.

Strictly speaking, I think time is a ray, with a beginning point in time.
