Sure, errors are "enlarged" as you say...but not disproportionately...the entire image is enlarged, so to speak.
In the sense that reducing quantization noise (in a perfect world such scaling would be done using integer multiples on the principle of preserving all original sample points as you suggest...even if the real-world difference is negligible to the eye. Heck in a perfect world we'd be watching native 1920 x 1080P DVDs!) makes low-level detail more easily visible, any errors or artifacts in the DVD transfer also become more apparent.
A good DVD doesn't contain such artifacts to distract at a 1.5 screen width...I guess that's my real point!
