Ye gods this is a horrible concept, so let's develop it further.
After you've assembled your pizza with the reverse claw machine, you need to direct a spatula under the pizza, and into an oven. When your pizza is done enough, you use the spatula again to drop it into a box. Then you get a box-claw machine which you use to place your fresh pizza-in-box onto a delivery drone. Make sure it's balanced! Finally, you're granted control of the delivery drone, which you can fly to your house.

What could possibly go wrong?
