With sudo you gain administrative rights (still depends on the actual
sudoers config) - in principle you can harm your system by mistake (sudo
 rm -fr /usr/lib/* ...). That is why it is normally not allowed on large
multiuser systems. It should be possible to use any non-system software
without it.
