The ruling on Moto Taigo has me confused.

Why is this not a perfect case of the card overriding the technical rules - the card itself clearly says you may target a card in any unit that has moved?
If not the above, Given that his Interrupt must be triggered before we find out if any cards have actually moved, then surely the targeting of his Interrupt may only target a card currently at the battle (as cards at the battle are the only legal target), and therefore would only destroy a card leaving the battle, and could NOT target a card moving in because it is not in the battle at the time of Interrupt?

Because it's not "a perfect case": there is at least one scenario where the card works as written without needing to override the rules. Therefore, it doesn't "need" to override them, it's just more powerful or versatile when it does. That's not the rule's intent, so we're wary of allowing that precedent.

Under Discussion.
The targeting doesn't occur during the Interrupt's resolution. Instead it creates a delayed effect. Targeting occurs later, after the interrupted action moves the units (remember that under IvE rules targeting occurs never before the action's resolution). Then Taigo's delayed effect will kick in, and as the Rule of Location forces him to target only units *now* at the battlefield, he can only use his Interrupt ability when the Battle action moves units into the current battlefield.
