We did.
Your argument to paraphrase is "uh, Gunk is poisonous even though there is nothing in the game to indicate it, and uh, SOOOOO poisonous it can make infinite poison arrows in a uh totally non-magical way"
In other words, its not a valid argument in the slightest.

Valid argument? It's just an opinion and is valid as yours ;)
You may consider Swamp Guck magic and I may consider it a naturally occurring radioactive ooze that is toxic and glows in the dark... that would be considered 'magic' to a Viking. Alternatively, it could be an extremely potent toxin, much like those obtained from the appropriately named Arrowhead frogs, which as I'm sure you're aware only require a tiny amount to be effective.
In any case, if we are to agree that it is magic, then is it a magical property of the Swamp Guck or has the bow been enchanted during the crafting? If so, what in the game indicates that we have learned the knowledge and ability to fashion such a magical artifact? Did we magically learn that too?
