Well if the atmosphere decides it's going to have a day off then I'll start to worry.

The temperatures generated by reentry are not just hot enough to vaporize a satellite they are way beyond hot enough to vaporize a satellite. I can't imagine any scenario where a satellite survives. In any case the vast majority of the orbits are controlled, Which means they come down over the ocean.

    Reentry survival is a materials question. If someone decides heat resistant ceramic is cheaper all is well until that cames down and we discover it doesn't vaporize like iron (or whatever they make it with)

    Yeah because that's likely. You do realise that everything that goes up has to pass inspections right they don't just let people do random things. Anything that gets put in orbit is verified by people way smarter than you or me. You really don't need to worry about it.

    There's lots of stuff in this world to be concerned about but being hit by the orbiting asteroid is absolutely not one of them.

    I would hope so. You seem to be under the mistaken impression I think the above is likely. It is possible is my point.

    It's not only unlikely it functionally impossible. It would require the complete collapse of every system in existence in order to be even marginally probable.

    You're wanting a system to re-enter under extreme heat, survive, and necessarily hit a populated area with enough mass to do destructive damage.

    Likelihood of that happening accidentally are so low is do not be worth calculating. But yeah I'm sure you have some sort of point.
