Sure. If you can drop kinetic projectiles from orbit or higher, you don't need nukes. But you have to build a lot of infrastructure to either get that mass up

Sure. If you can drop kinetic projectiles from orbit or higher, you don't need nukes. But you have to build a lot of infrastructure to either get that mass up there, or compel that mass to change momentum. One drone with a shaped charge could take out a fueled launch vehicle and make the bad unusable for an annoyingly long time. I hope that there are plans to defend against this.
