To be honest it started as a kind of comment to another thread, but I believe it is good topic as is.

Yes, Inquisitor can just commission a ship - but it's INQUISITOR, not his acolytes. Acolytes for sure have some power from their master, but they are not even Throne Agents. And Inquisitor isn't just a storekeeper. So, in my game it looks like something like that...
Acolyte go to his master and ask him about "m'lord, can you give me plasma gun, to pop heretics with it?"
Master looks at him and... well, variations.
0. Acolytes are sent to the difficult mission with expected heavy firefights with armored targets. "Hey, I told you to go to storekeeper - you know where he is - and tell him to give you two plasma guns. But you should return it to the stock. This technology worth more than you."
1. Acolyte is high-rank, have good dossier and can fire that plasma gun. Or he is a lover for his master (why not?). Or Inquisitor have good plans about him, something about Investigators and so on. Or he have good night sleep so is very kind today. "Oh, yes. You're proven your value so I can give it to you. Well, you're good, so I will gift it for you. Do you want some kind of memory plank on stock?"
2. Acolyte is middle-rank, Inquisitor isn't very fond of him and so. "Well, why you need it? I understand you want it, everybody do. But convince me that you really need it!"
3. Acolyte is low-rank, or maybe he is known by his habit to lose (or even to sell) rare equipment, or Inquisitor have a hangover or just is a jerk (that's really possible!). "No. Dismissed."
And don't you forget - your Inquisitor is a busy man, he have another business that secure plasma gun and a crate of best-quality lasguns for you. Even if HE can just go to the Tricorn Palace and take one from armory.
About ""disappear" forever"... well, in my opinion this is kind of exaggeration (even when placed in rulebook), I should to admit. I lived (he-he, just four years, but I read about a lot!) in USSR, there was KGB and so on. And if KGB just recruited you as secret employee , that didn't really means that you're disappeared (because THIS can raise questions too!). You're working on your previous work, hanging around your contacts, maybe even have a hand that push you in your career. And yes, your superiors don't dare to ask (read it as "your master use subtle influence checks to put you from your work to do some another suicide mission without Rosette flashes") - they even shouldn't to know that they have a reason to ask. Some superiors ask that particular man to go to business trip. For, well, Cindar. From Malfi. That man will not be here for, ahm, a year or something. But you will continue paying him salary, that's a orderliness.
When you start your cadre working for Inquisition directly... well, that's Ascension, you're named as Throne Agents and you, I should notice here, have no problems with money, just availability.
And yes, there is some danger in "to be caught in random investigation". Or with questions "why couple of adepts can need a crate of lasguns". Well, you should be able to solve it, and better - without your Inquisitor help.
It's kind of modules itself, and with my party we played it with some frequently. But we love playing live in Imperium and saving it from countless terrors, not just save it form countless terrors. It's not so fun, after all.
And after all, it's - I mean "you continue to live your life, but there is something more in it" - one valid explanation about career paths at all. Why have you be stucked to some common skills and talents (and, after all, ranks) if you live without bonds of society? Only War system will suit "living outside" better.
But if you have to live within society, and live here with discreet - career paths are usable enough. You're Administratum clerk (soldier, scum, Imperial Psyker, tech-priest), who works for Inquisition from time to time, so you're bonded to this role. Yet.
