Yes, and there´s nothing condescending about this.  A student who is too
chicken to try out basic things, be it within dedicated testing environments
or, if need be, otherwise, will not become a good admin and is probably
not a person well suited to bearing the responsibility that will be bestowed
upon them, partly due to a lack of good judgement.

I think that is something you should teach your students --- in the hope that
their attitude may change.  Isn´t that your intention to begin with?
