Likely same reason as many, many other things: the modern 'automated' version (tie wraps usually) is easier, cheaper, faster. And has the standard consequences which unfortunately get ignored: requires close to no skill, plastic, seldom reusable, probably won't get recycled and ends up as waste eventually. Lacing has some of those disadvantages as well though.
One big problem with lacing is that it's one long string of knots instead of many individual tie points. You can always cut a zip tie and replace it with another. For lacing that was cut in the middle fixing is a slightly more involved process. So unless it's a final install it could bring some headaches. It's very unforgiving if you realize you got something wrong. With regards to the material used, I have never use…
Only if you are speed lacing and do not knot the intermediate restraints. If there is any chance that you will need to break apart mid line you add a stable knot at each intermediate and can simply break between any tie.
