I started out baking measuring by volume, and it's not like it doesn't work. You can make amazing things basically measuring by handful, pinch, and feel. I think technique and ratio are more important than careful measurements.

Everything else is optimizing for consistency, which might not be important to everyone. If you care about it, measuring by weight is more accurate. The undesirable variations aren't usually taste, but structure and texture, which can be noticeable.
