This.

The acquisition system might look simple at first glance, but when you start to modify it to make it able to properly represent things it isn't quite capable of in its pure form (such as one-off rewards and payments), it quickly becomes so complicated that its purpose is defeated. I tried, and that was when I still was convinced there was no other way than acquisition.

That would, like most things, depend on the planet. There is no Imperial constitution stating that every planet needs to be grimdark, oppressive and miserable.

Living hand to mouth does not mean you have no money. It means you have no disposable income after having bought basic necessities and paid rent. But money still passes through your hands. Unless the planet is one big centrally planned economy, whoever employs you has no way of directly providing you with everything. Instead, he pays you money, which you pay someone else to get the stuff you want. A monetary economy is absolutely necessary in any system with independent, specialized economic actors.

You can't, unless it's an add-on for a weapon armour (like the example is given in the book, you can add a -5 modifier for getting a red-dot laser sight on your lasgun (using the highest of the rarity of the two as the base rarity modifier) and then roll to see if you get a lasgun with red-dot). You can't combine rolls for grenades, armour and guns all into one roll, you have to do them separately.
