Trust me, I spent three years at the Naval Space Command. Solar storms can and have deorbited satellites.
I trust you and I did not mean to dismiss it all. If you checked my posting history I often say that a solar flare or storm is a far more likely scenario than an EMP to take out our electrical grid.
We have had some pretty strong ones in the last few decades (and before I am sure) after I became aware of the risk and I was not aware of the US losing satellites and you taught me something - not sure how I missed this (link below).

That was not cheap!!!! Hope our military satellites are more hardened than the Starlink ones were.
