You were basing your decision of Alignment and Manufactured Weapons off of the Alignment Subtype definition.
You're utilizing the Alignment Subtype information only in your analysis. That is a fundamentally flawed approach.
So, you would say that Manufactured Weapons that are magically enhanced to have an alignment (but not the relevant alignment subtype) do not bypass the appropriate DR?
RAW disagrees with you.
Holy and Unholy are the same. Nowhere does the weapon gain the alignment subtype, it simply becomes 'aligned' or, rather, gains an alignment. Alignment does not equal Alignment Subtype, as I believe we agree upon.
Weapon Type and the Wielder matter because you were using the Alignment Subtype text (which only a creature can have) to make a decision on manufactured weapons bypassing DR that have an alignment, but not a subtype; the text relating to weapon enhancement state that a weapon merely needs to be aligned or have an alignment to bypass the DR - the weapon does not gain the alignment subtype.
Alignment Subtype text doesn't tell us anything about when something doesn't have an Alignment Subtype, only when it does.

Emphasis added.SRD said:Anarchic: An anarchic weapon is chaotically aligned and infused with the power of chaos. It makes the weapon chaos-aligned and thus bypasses the corresponding damage reduction. It deals an extra 2d6 points of damage against all of lawful alignment. It bestows one negative level on any lawful creature attempting to wield it. The negative level remains as long as the weapon is in hand and disappears when the weapon is no longer wielded. This negative level never results in actual level loss, but it cannot be overcome in any way (including restoration spells) while the weapon is wielded. Bows, crossbows, and slings so crafted bestow the chaotic power upon their ammunition.

Axiomatic: An axiomatic weapon is lawfully aligned and infused with the power of law. It makes the weapon law-aligned and thus bypasses the corresponding damage reduction. It deals an extra 2d6 points of damage against all of chaotic alignment. It bestows one negative level on any chaotic creature attempting to wield it.
