>It's kind of insulting to assume that students are unable to decide what's good for them.
It's also kind of insulting to assume that teachers with decades of experience don't know how students behave.
Student cheating or working is not binary; it's a continuum. There are plenty of students in the middle of that continuum that will copy answers and not learn if answer are easily available, but that would do the work if answers are not available, and those students are better off having to put in effort when they don't have easy answers.
