You can't ever finish adding epsilon infinitely often, so everything after that is dead code. There is no "now" to speak of.

The same thing comes into play when you speak about an infinite number of zeroes after the decimal point and before the last digit. There is no last digit. You could have numbers with two "ends", but the so-called real numbers are different. They stretch infintely to the right, without end in sight.

There are also p-adic numbers, which stretch infinitely to the left, but they behave very different from real numbers. https://en.wikipedia.org/wiki/P-adic_number
