I'm a new member here, and I thought I'd say "hi" by starting up a new topic on something that's bugged me for a bit, and maybe get a fresh perspective on it. Forgive me if I'm putting emphasis on something that everyone else thinks is obvious

Regarding the titular question, I sometimes feel that it can be very true. This isn't the case for items that are obvious to any observer, such as a firearm. Licenses for those pretty much are mandatory if you don't want constant problems with the law. However, for non obvious gear, different combinations of gear do seem to make me think taking licenses for them are pointless. Take for instance, the following case:
Obvious Cyber Arm
Strength Mod X
Spur
Now, I'm making two assumptions here. My first assumption is that the Strength Mod on the arm is a modification to the internal workings of the cyber arm, and is not obviously noticeable without special equipment (i.e. a cyberware scanner) The second assumption I'm making is similar, but in regards to the Spur. Because Spurs are retractable, I assume that when retracted they are unnoticeable. I figure this is the case because RAW lists no threshold to detect retracted Spurs, though I do realize that this could also mean that they
are in fact obvious and not really hidden at all. The first interpretation just seems to make more sense to me, but I will admit it's highly possible I'm wrong.
Now, assuming I'm correct, MAD Scanners arn't that big a deal, because they'll just detect the cyberarm and not the equipment within. Easy to play off and no licenses is need for either in this situation. As I'm sure we're all aware however, Cyberware Scanners are another case entirely, because they see through objects and can pick individual equipment in the arm. So, the character gets scanned, and the scanner gets it's hit and detects the arm, the Mod, and the Spur. Here's where my question starts to come into play. The Strength Mod is restricted gear, so one's first instinct is to buy up a fake license to make it nice and legal.
However, the same scan will pick up the Spur, which is forbidden equipment. So you're going to have issues no matter what. So it would seem to me that one ought to just save yourself the [100 x rating Nuyen] on the license, cause it doesn't seem to matter.
Now, you might say, "Big deal, at char gen that like what, 400 Nuyen saved?" Well, that's just for the arm. There's still the rest of the runner to consider!
Runny McRunsalot
Eyeware
Cybereyes 1
Cybereyes
Smartlink
Bodyware
Plastic Bone Lacing
Wired Reflexes 1
Dermal Plating 1
Reaction Enhancers 1
Muscle Replacement 1
Obvious Cyber Arm
Strength Mod X
Now, you'll notice that I removed the Spur from the character, and you may be wondering, "why?" Well, it's because I'm open to the idea that a Spur is in fact obvious to an observer. So I've replaced it with a piece of equipment that I think we all can agree is not obvious, but is forbidden just the same (Plastic Bone Lacing) The rest of the gear is either restricted or perfectly legal.
Now, the character goes through a MAD Scanner. It'll go off, but again this isn't necessarily a big deal. Almost all of the gear cant be seen with the naked eye, and the cyberarm can be played as the source. Hell, the Bone Lacing cant even be detected by MAD because it's plastic. But again, a Cyberware Scanner will pick it all up. Since you have a piece of forbidden gear, having licenses for everything else would seem to be pointless. Now we're up to 2400 Nuyen. That's somewhat significant at Char Gen, at lest it is to a skinflint like me! I mean, c'mon that's like, 240 doses of Novacoke! Could throw a hell of a party with that! And there's a hidden bonus as well. You're SIN doesn't need to have a background explaining why you have all this murder gear installed in you!

Am I wrong in my thinking? What do you all think?
Now, I will say one more thing, when I talk about MAD Scanners, I'm assuming a walk though scanner. Because MAD Scanners can be wands too, the character would want to have at least one license, probably for the Dermal Plating, to explain why their calves are setting off the scanner.
