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.
Except the space in these orbits is finite and a collision at say 520 km requires quick action or the entire fleet in that orbit will eventually be destroyed.
