Problem is this capability is concentrated in the hands of
1. A private company.
2. Of a single country with inconsistent leaders.
I’d be less anxious if Europe had this capability instead.
Europe isn't the sort of place that would develop this capability
I don't like that either, but nothing's stopping others from following the same path and achieving the same capabilities, other than their own inability or refusal to do what's already been done. It's been over a decade since Falcon 9's first successful landing and we're only recently starting to see similar feats from others.
You will be fine. China will have this capability soon.
