Given the proliferation of anti-satellite weapons, agile launch capabilities have become just a basic requirement to win any high-end conflict. Satellites aren't survivable so we have to plan around a high level of attrition, with replacements stockpiled and ready to launch within days or hours.

Agile launch capabilities, but also cheap launch capabilities. Which is another area where SpaceX (comparatively) shines.

Western Aligned Militaries also have things like Global Hawk and stack and stacks of other toys that can fill a tactical surveillance niche.

Can always put in space sensitive equipment that you wouldn’t want shot down by “simple” surface to air weaponry and their technology exposed to the adversary.

There's like a big jump in platform cost and capability (downgrade) wise when you throw a satellite up. Putting a new ISTAR package on a drone is a lot cheaper than making changes to a satellite.
