@fakescorpion:
I think at this point we’re arguing over completely different things. Cracker is not baking those biscuits, but he needs to know about them to fully utilize them, it is literally the same for all devil fruit users.
Why does Cracker need to know about the production of biscuits when that's the basic thing the fruit does? The cookie dough leaves his body and then hardens into a biscuit. It's the freaking name of the fruit - BISCUIT BISCUIT.
No one needs to be a chef in order to utilise that basic functionality. He's basically Mr. 3 reloaded, who created wax that was hard as iron, but he was also a gifted artist who could sculpt the wax into various tools before it hardened. Anyone could produce iron-hard wax with his fruit, but few could form it into a mecha suit or a gigantic, candle-like work of art.
Caesar Clown needs to have proper knowledge about gas and chemical interactions to use df to more potential, you think someone like Luffy who probably couldn’t spell oxygen would be able to know manipulate air components to suffocate people? There is a reason Cracker has to be a chef, there is a reason Ceasor Clown has to be a scientist, and there is a reason Law has to specifically be a surgeon (and not a physician) etc. If you could understand this concept for people like Caesar Clown and Law etc., but completely failed to grasp the exact same concept for Cracker, then that is all on you.
No one needs to be a doctor to create a Room with Law's fruit and no one needs to be a scientist in order to emit gas with Caesar's logia. Are these fruits in the best possible hands, with both users realizing the full potential? Yeah, sure. But they are not inventing the basic functionality.
If you could understand this concept for people like Caesar Clown and Law etc., but completely failed to grasp the exact same concept for Cracker, then that is all on you.
You called the biscuit fruit "objectively lame", and I believe that's because you deny the fruit even it's basic ability - creating biscuits. But why would the user of the fruit need to know a thing about the creation of biscuits when the fruit does exactly that already? It creates biscuits! Cracker doesn't need to know about the correct ratio between sugar, butter, flour, eggs and salt in order to create biscuits, the same way Galdino doesn't have to know the exact mixture of hydrocarbon molecules in order to emit wax (he's an artist, not a chemist - and because he's an artist he creates wonderful wax-mecha suits and giant candle constructs of doom).
The entire character of Cracker is Oda paying respect to chefs that are also food artists. Cracker's art skills don't make the biscuits more biscuity, but he can fool his enemies into thinking that his puppets are real because he's just that good when it comes to sculpting food. That's his unique take on the Devil Fruit, other users wouldn't be able to do that.
That's also why the biscuit fruit isn't objectively lame, the same way the mochi fruit isn't objectively lame. The ability to emit ANY substance in unlimited quantities is incredibly useful, especially with haki coatings and other shenanigans. And there are actually very few of them around that aren't classified as logia.
Seriously, I would even take a Poop-paramecia over most other fruits of that class.
Do what Katakuri does, just with poop.

I could even become a poop-artist!
