It's a weird comparison. I rarely wear heels, only on special occasions. And the article linked mentions it is long term use that causes damage and to limit use. That is what I a lot of other women do. Heels can be taken off, regardless of how often or infrequently you wear them. Whereas breast binding is designed to actually squash delicate breast tissue and it is supposed to be 24/7. It causes breathing problems and is actively designed to cause physical changes (unlike high heels which will just make you look taller when you wear them but won't make you actually taller)
