More precisely /bin /sbin /usr/sbin all links pointing to /usr/bin yes but /usr/local is still of relevance and /opt although it really feels like opt (which doesn't have a great semantic meaning and would be better suited for something under /usr/local similarly /lib and /lib64 are pointers to /usr/lib It might be interesting in a vm to remove those symlinks and see what breaks. Presumably a lot.
