This is kind of that 'climate change skeptic' argument that CO2 is only a tiny percentage in the atmosphere, 0.04%, so anything humans have done to that tiny percentage is therefore negligible. But we've had a massive impact by increasing that tiny percentage by 50% causing climate change.

But how much of that is aluminum? Probably <0.5%.

Nit: You're off by about a factor of 3 because it's 14.6 t/day.
