A thought experiment doesn't have to replicate reality.

For instance---you are taking a class which you paid for but some students did not. You see a student helping another during a test----clearly cheating. Do you turn in the cheater, do you tell the cheater to stop but take no further action, do you demand some free right answers yourself? if the cheater is a friend .... if the person getting help is your friend ... if the person giving help got free admission ... if the person getting help got free admission ....

If the description and options are sufficiently wide-ranging and specific, people can pick a choice comfortably. if the scenario is unrealistic or the options are not sufficient (do not include obviously real and reasonable courses of action which you would take, while all those offered are not what you would really do) then the thought experiment fails.

IMO.
