You're right. In fact a time loop has the same something from nothing problem any other theory has.
Imagine a flatlander universe. Package up time in another dimension and you can represent their entire existence as a static 3d cube. Timeloops would just be a static torus in the cube.
The same is true of a 3 spatial dimension + 1 time dimension universe. You can view it as a static 4d tesseract. Timeloops are just a 4-taurus. Where did that 4 Taurus come from? It's the same something from nothing problem.
