Putting "NO SID/NO STAR" in your flight plan won't keep you from being required to fly a STAR, just force ATC to read you the whole STAR verbatim and annoy them royally, as well as making you copy the whole thing down in flight. That phrase is a holdover from 40 years ago when SIDs and STARs were created, and they were published in a separate book from approach procedures. Most light plane pilots didn't bother getting the separate book, and they were permitted to note the fact that they didn't have copies of those procedures aboard to let ATC know they would have to read the whole procedure to the pilot. Since SID's and STAR's are now integrated into the Terminal Procedures books along with all the approach procedures, there's no point in putting that remark in your flight plan unless you like writing down a long and complicated clearance and annoying ATC to the point of possibly being put in a punitive hold until they have time to read you the whole thing.
