I’d like to hope that in a few years when we collectively decide this was a bad idea we can start hitting them with lasers and ablatively decelerating them to burn up in the atmosphere.

If we do nothing at all they’ll burn up in 3-5 years anyway. Starlink operates in a very low orbit. Thats one of the reasons there have to be so many of them. A higher orbit (like MEO instead of LEO) would mean fewer needed satellites for the same level of coverage of the Earth.
