Goumindong, I am simply amazed by your tenacity. Your entire argument rests on "well, even though the Player's Handbook explicitly states one thing, I'm going to contradict the rules, claim that the printed text is a typo or a mistake, and insist that my interpretation is what is intended by the game designers."
It's a bold position, my friend. An unwinnable one, but bold nonetheless...
Uhhh. Read page 224 again. The players hand book explicitly agrees with me and explicitly disagrees with those who argue against me.
Furthermore those who argue against me support rules that end which, if they are true, necessarily support ridiculous situations such as heavy armor users getting dexterity or intelligence to their AC(since they can just wear cloth armor under it and get the benefit from both), or a player getting a plates Base AC, and a cloths enhancement bonus and special qualities.
Rules start with their general meaning and then end with the specific implementation of that rule. This can be seen in every single situation in which a rule is described in the book. Earlier i used the shifting rules as an example, because half the people in this thread were also in a discussion regarding shifting and agreed that the rules text of "Shifting does not provoke OA" was not the rule for how shifting worked, but instead the rule that came right after that, which described exactly what shifting did was the relevant rule. Specifically that shifting only prevented OAs from leaving an adjacent square. It did not prevent any other OAs pinging on movement.
Here is thee rules text that is General:
"You can benefit from only one magic item that you wear in your arms slot even if, practically speaking, you can wear bracers and carry a shield at the same time."
Notice how it says "wear" and "Carry" and not "use" and "wield".: This means that you can indeed put bracers on and carry a shield, nothing prevents you from sticking the items there. Nothing prevents you from holding a dagger in the free hand a light shield uses, but that doesn't mean you can attack with it or gain two weapon fighting benefits form it being there. But something does prevent you from gaining mechanical benefit from that use.
The Specific Rule then follows what is essentially general reminder text, or introductory text depending on how you look at it.
This is that specific rule:
You benefit from the item you put on first; any other item you put on doesn't function for you until you take off the first item."
Note, in order for these two sentences to both be true, the second sentence must be the rules text. If it is not, then you are claiming that this text for some reason is not rules text, yet somehow the text right in front of it is.. These two can be true if the second is true, because all magic items are also items, even if all items are not magic items.
So there is the problem that the people against this are failing to meet two basic requirements.
1. They are failing to read the rules as written. The text, even if its in the magic item section, refers to items.
2. They are failing to read the rules as intended. Rules as intended are not intended to allow contradictory situations(I.E. A fighter with a sword and shield dual wielding by holding a dagger in there shield arm). And the rules as they are reading them must necessarily support these contradictions.
According to you folks, i can wear and benefit from as many different armors as i want and gain benefits from both of them since non-magical armors do not take up a slot. Note that for the majority of a players career this entire negates the section of magical amors dealing with item type. You want a troll hide platemail? Just put on magical troll hide over or under mundane platemail. You get the enhancement bonus from the troll hide, the armor AC bonus from the Platemail, the light armor bonus from dex/int for wearing light armor and the special benefit of the troll hide. Wooo, congratulations, you're 2-3 AC(or more) above the guy actually playing by the rules until the late paragon tier where now still ahead by 0-1 until the late epic tier. Cost of the extra AC? 50 gp.
