Lasers would probably be more practical. Maybe a whole array of lasers w. telescopes? At (say) 500 km, a 20 cm aperture would have a spot size of maybe 50 cm. So let's take that telescope array, hook a kW laser to each one, and roast some LEO satellites?

(Note: this is not an actual suggestion this be done.)

I know you are joking on this one, as I was on mine. But with people being arrested for shining pet toy lasers at objects, best everyone stay clear of this one.
