Again I'm not asking for support to raise the cap, I'm just pointing out it could be raised and that we should stop referring to it as some aspect of Bitcoin that is mathematically limited by fundamental laws of the Universe because its not, its consensus limited.
I feel like you are splitting hairs. It can be shown using math that under the current rules the number of bitcoins is limited to less than 21 million.
On the other hand, it annoys me when somebody claims that something has been proven "mathematically", where "mathematically" is intended to mean that the evidence is very strong.
