You can explore a GUI if it’s safe to do so. If a user has been burned by easily putting their system into an unrecoverable state, they develop a fear of exploring. “I don’t want to change anything; I might break my computer / lose all my work / get a virus!” is a really common fear.
That’s an argument against bad GUI design [Edit:, not GUIs in general]. This can just as easily (if not more easily) happen in CLIs, where a single typo can fuck you up.
