You're always welcome to argue with me! 
It's nothing to do with the sweeteners (although it will always, even after Bootcamp) be a good idea to avoid those, as they mess up our gut biome. It's about the sugar and the sweetness level.
Sweet things give us a dopamine hit. Just like alcohol or drugs might do - it's the reward centre of the brain. Which is why we crave them. I'm guessing that there aren't many of us who regularly crave broccoli in the same way!
By going low carb, we're aiming to cut/reduce the hold over us that sugar has. And, as countless Bootcampers have said over the years, you will find that your taste for sweet things does wane. A good example is the Montezuma chocolate. If you'd told me years ago that my regular chocolate consumption would be 100% cocoa I would never have believed you. Now, if I eat ordinary milk chocolate, I do find it very, very sweet.
You're quite right that it's good to have low carb recipes up our sleeves - and desserts can be particularly challenging. I was just trying to point out that at this stage, planning for sweet things suggested to me that perhaps you're still craving sugar/sweet things.
