> The convention "everyone" uses doesn't stop being arbitrary just because most people use it.

Except conventions derive their value from the proportion of people using it. If a convention is stupid for other reasons, it may be worth trying to convert people. But writing numbers without a leading 0 is not stupid; in fact the opposite is. Why not write the current year as 0000000000002022 to preemptively protect against the Y(10^16)k problem? Why not write your age as 027 so that you're prepared when you hit 100?

> The mind you save could be your own.

You telling people you're liberating their sheeple mind, like literally every conspiracy theorist says, is not helping your case.
