The service provided by TLG is very good. I have a 'wheel' missing from my Tower Bridge and a 2x3 light grey from my Death Star. (Separate cases) They were shipped for free and it took about 2-3 weeks as promised for them to reach Indonesia. There were no questions asked, and they didn't ask me to prove anything. I actually fear for the TLG that the system might get abused. I'm not sure if rare parts are replaceable, thankfully all that were missing from my sets were common ones.
That being said, I believe prevention is better than cure. I think the missing part monitoring system needs to be adjusted. From a Lego documentary that I watched, it seem that they rely on weighing the sets to ensure that nothing is missing. But the result is a lot of extra, unnecessary useless parts while there still is a possibility for a missing part.
Weight checks are one of the most trusted means of checking mass-produced items to ensure they have the right quantity of contents. This applies to everything from LEGO sets to boxes of cereal. TLG probably also uses other means of quality control, like checking one set per batch to see if there are any omissions. But with mass-production at TLG's scale, it would be impossible to manually check each package individually for completion.
Thus the weight check is invaluable: it's the best means they have of ensuring quality control for
all sets produced, not just a few sample sets from a batch. Errors get by the weight check occasionally (in a particularly egregious example, my younger brother once got a BIONICLE set with a red 2x4 brick in place of the intended silver shoulder armor piece), but far more would get by if TLG didn't have the option of checking every box in some way or another.
As for the uselessness of extra parts, that's a matter of opinion. Sometimes the smallest parts are the ones it's most useful to have multiples of, like 1x1 tiles for SNOT brick lettering and mosaics. Remember the outcry there was after the Collectible Minifigures stopped including extra parts? It wasn't huge, but there were some people who felt very strongly about getting extra minifigure accessories.
