Thank you @whyaskwhy I followed you just now. You make a good argument, but I'm still not convinced that starting from 1 is the best way to do count or do math. I think some parts of mathematics work like magic and are immutable because if they worked any differently then they wouldn't work at all, while other parts of mathematics (in this case, the way we count) are more of a cultural preference. So what if I don't agree to everybody else's preferences?
It's a little bit like how everybody just uses Base 10 as if that's how math is supposed to be. If I told you that B + 4 = F then you might call me crazy, but I would just be talking about Hexadecimal (Base 16). The cultural-preferences that we take for granted as mathematical certainties are nothing more than normalcy bias.
For example, if you were raised in a culture that starts counting at 0, or counts everything in base 3, or even a culture like the Mayans who labeled their numbers with dots and lines, then that's just the way you would be used to doing math, and any suggestion to the contrary would seem ridiculous.
All I'm saying is that counting from zero doesn't break any real math rules (the only thing it breaks is culturally accepted norms). It's just a matter of preference so far, at least until someone discovers a need to count from zero.
I'm only guessing that at some point in the future counting from zero may become a necessity for some reason, until then I'm more than happy to point out the absurdities of counting from 1 :)
