As per usual, we tend to do things like this without thinking through the whole process. Current research suggests that the massive quantities of metals burning up on re-entry are once again destroying the ozone layer. There may very well be other yet to be discovered issues/

There are currently over 10,000 satellites in low earth orbit. That number is rapidly and dramatically increasing, with Starlink alone planning for another 30,000 added to their existing constellation. The other providers are certainly planning to follow that trend. Eventually all of these satellites will de-orbit and burn up.

A few satellites burning up may not be a problem. But 10k, 20K, however many tens of thousands, will eventually make the problem that much more serious.
