I think you missed a factor of 1000 somewhere in there: Each satellite weighs about 1 ton, there are about 10,000 of them. That is 10,000 tons in orbit for the constellation, not 10. Assuming a 5 year decay, that's 10000/5/365 ~= 5 tons / day. Still about 10% of the natural incoming material, but considerably more than your "six hours worth per year".

I did. what. the. hell? Maybe my swiss-cheese brain read the "," in 10,413 as a decimal separator? I guess that's what I get for posting while old. Thanks for the correction and supporting arithmetic.

Though, I still stand by my "please for the love of everything, get to complaining about CO2 because this thing you're complaining about is a damn nothingburger" conclusion. (I am sufficiently aware to notice that that you're not OP, so the "you" in that pseudoquote is not directed at you.)
