Destroying these satellites with lasers poses a similar problem to what happens when you light zombies on fire: the satellites are held in space by their momentum and the reduced atmosphere vs Earth’s gravity. If you break the satellites into pieces via laser, then now you have uncontrolled and unpredictable space junk to deal with. Some of the pieces might return sooner, but what was once a concern is now a problem. Just like a zombie at your door is very concerning, a zombie on fire at your door is an immediate problem.

Now, what could be interesting would be sending up another satellite that sprays black paint on the sun-facing side of other satellites. The energy absorbed and then exhausted could propel it towards Earth sooner. Maybe? I dunno, I’m just a simple country Fartographer, your honor.
