Okay, the stumbling block for me is the idea that WotC would actually expect their players to jump through these logical leaps rather than just seeing "wand that shoots fireballs as an action" and thinking "okay, sounds like this qualifies for my cool ability".This is exactly right. And we should be able to find an example where B => A is clearly not intended.
Once again, the precise words:
RAW: [use a bonus action to] Take the magic action to use a magic item that requires that action. (granted, this phrase is awkward)
Crawford/Intent: "The thief will be able to take a magic item that requires a magic action for activation and thanks to fast hands, activate it as a bonus action."
Applying the intent to the rules: [Use a bonus action to] Take the magic action to use a magic item that requires a magic action to activate.
Reversed: [Use a bonus action to] activate a magic item that requires the action to be a magical action.
Is there an example where the reversed statement is clearly unreasonable? yes. The simplest might be:
A magical "+1 to DC "Holy Symbol. "You can use a Holy Symbol as a Spellcasting Focus" to cast a magic action spell ... now as a bonus action. (PHB says holy symbols can be "used" to cast spells).
Whereas many DMG magic items are clearly matching the exact wording of the intent: "As a magical action you can ...."
