Would you apply the same standard to self defense, which is an "armed attempt to intervene in crime"? Think of mercenaries in this case like Uber drivers, people "below the API". If I shoot a robber in my house it's ok (and already more or less legal). If I hire a full-time security guard and he does, that's also ok. Both things happen regularly all over the place, is it somehow "horrifying"? Alas, I cannot afford a security guard any more than I can afford a private driver, hence a part-time app-based security guard (or driver). It doesn't replace the police, and is accountable to the law and police; it just a tool to solve a problem.
