Whats next
There are lots of ways to kill your self flying a published approved instrument approach, like descending below minimums, loosing control during the transistion to the missed approach etc etc. This is a reflection of a lack of basic pilot decision making abilty, preofessionalism and judgement, just like what would be demonstrated by a pilot flying a made up approach in actual IMC.
If the student cannot comprehend that the purpose of utilizing a commercial radio beacon in good day VFR is to practice an instrument procedure and one is never to actually fly an unapproved approach for real, then I would suggest they are not competant to hold a pilots license.
I think we have beaten this topic to death and I do not intend to further comment on this as frankly I find your posts patronizing and and unconvincing
