I do the same. I don’t plan to take it apart but wood glue is part of any woodworking shop and I don’t see why assembling Ikea should be qualitatively different. I want my assemblies to stay together, not vibrate, to feel sound. Gluing joints is fundamental.

This is the way.

Even the cheapest cardboard-filled IKEA units hold together much better when glued, and makes moving the units less stressful (no more "it's creaking / skewed when I pick it up").
