Linking /bin /lib /sbin

Hello,

I am building a LFS system, I won't go as far as building an elaborate graphical OS, just a minimal one in order to better understand the inner mechanisms of GNU/Linux.
I am at the creation of the limited directory layout step.
At this point:

for i in bin lib sbin; do
  ln -sv usr/$i $LFS/$i
done

I understand what this command does, but I need explanations regarding its utility in the system (there's no further explanation in the LFS book).
Thank you.

It's because lennart broke it, then broke it again and complained to not blame him because it was already broken before

(tbf, others had broken it, too - he could however have mentioned his part in the list he enumerates there…)
