You have made a hand-wavy gut-feeling conjecture about the amount of human-produced ground sources of aluminum in the upper atmosphere. You have given no stats. I have linked to several papers and articles by people whose research (scientific and journalistic) say that, yes, the demise of megaconstellation satellites will significantly increase the percentage of aluminum in the upper atmosphere, with potentially negative effects like thinning the ozone layer. Your belief about ground sources necessarily implies you believe all those researchers must be wrong.
