De-orbiting satellites by burning them up did work when the volume of satellites was small, but already 10% of aerosol particules in the stratosphere contain aluminum/other metals.
The problem is only going to get worse with the launch of megaconstellations https://www.pnas.org/doi/full/10.1073/pnas.2313374120

seems we are rapidly building a Faraday cage for our planet, suppressing our protective magnetic field, because we don't have enough problems down here already
"So far, models of spacecraft reentry have focused on understanding the hazard presented by objects that survive to the surface rather than on the fate of the metals that vaporize."
