and Musk can't even get US security clearance, he's not allowed into certain SpaceX hangars during some operations

I'm no fan of Elon - but the historical norm is that only gov't and local forces operate in major war zones. Vs. foreign companies either keep their distance, or at most operate with direct military escort.
You're fudging away the critical distinction. How many of the 100,000+ tanks, warships, and warplanes built by US corporations during WWII were operated by those corporations in combat zones? Extremely close to zero - because combat operations were the job of the US Army, US Navy, USAAF, etc.
No, I don't like Mr. Orange either. But he is the current POTUS. Starshield is under his control. And his failures do not obligate Mr. Musk to step up and serve - any more than they obligate young American men to serve in the Ukrainian Foreign Legion.
