The only reasons I can understand for NOT tying a quilt:
1) Some battings/waddings shift and bunch up when the item is washed
2) Sometimes the ties come undone
3) One does not care for the look
4) If one used a very thick needle, one could possible break some of the threads of the fabric.
5) If only a few ties are used - there could be a lot of stress on the fabrics where the ties are if one is using some of the polyester bats that are not needled.
Like almost everything else in quilting, there are many variables involved - so a technique that is appropriate and works well in one instance - may be a poor choice for another project.
