Zip ties are 'quantized' by the ratchet, so you can find an 'optimum' tension point that is between two ratchet points. Which doesn't happen with laces.
And for threads (like kevlar thread) it doesn't have the compression strength to be good zip tie. There is a lot of information about what NASA considers to be good and not good wrapping techinques here: http://workmanship.nasa.gov/lib/insp/2%20books/links/section...
Also they mention out gassing which is something I completely missed, plastic zip ties have that issue as well. Any void in the zip tie also becomes a real problem in vacuum.
