I mean... honestly, speaking as someone who's been a teacher, I have no particular problem with classroom practices requiring students to put in a good-faith effort on their end to do things properly.

Generally speaking, in any class I've taught above the eighth-grade level, homework is optional anyhow, so turning in an essay written by someone else would be exceptionally pointless.  Can you get some points for dutifully turning in every assignment?  Sure.  You can grab basically enough to round up from a high C to a low B, so it's a good idea if you're struggling (as is, y'know, doing the homework so you learn what the course is teaching).  Probably those points are literally going to be tied to whether you turned in the homework at all, not what your marks on it were.

The homework is there solely as a study aid for the student, in the same way that optional review sessions and Q&A sessions are there for anyone who doesn't feel like the information fully clicked from the lecture alone.  It's a way to practice applying whatever the class is teaching with an instructor's direct feedback in the form of marks, so you know what you need to put more effort into before the test / oral presentation / etc.

The actual assessments of whether you've learned are proctored, primarily because that's how applying knowledge works everywhere else too but it has the bonus of making academic dishonesty extremely hard to pull off beyond shiat that most competent teachers will let you do anyway like bringing in a note-card's worth of formulas (outside of the class you'll also always be able to access basic notes like that so there's no real reason to deny them; one PI I taught for was a little more old-school and literally just attached a sheet with every base formula taught in the class to the back of the tests himself).

People who've only experienced teaching from the student end sometimes have a... frankly insane lens on how antagonistic the system actually is.  Very, very few teachers in secondary and post-secondary education view themselves as "authority figures" to be opposed or obeyed, their view of the relationship is almost invariably that they're knowledge resources for students to take advantage of.  Stories like frat houses hiding away old exams so you can 'get the questions early' always make me chuckle a bit because... the absolute #1 most common study guide handed out by TAs in pre-exam review sessions?  Literally just a copy of a previous year's exam, complete with the high-scoring answers.  For essay-heavy exams it's fairly common to, y'know, give students the actual questions for the upcoming exam, more or less.

Like... obtaining some approximation of what the exam is about and what the questions will be, and formulating potential answers to it in advance?  A lot of students have this weird imposter syndrome shiat where they think they're getting away with something.  No.  That's... that's just studying, my dudes.  That's what you were supposed to be doing.  You are an adequate student who's got some of the basics down, good for you.  The point of the exam is that the questions cover the subject matter the course is designed to teach you.

// In a sane teaching environment overall course grades / exam grades are more of a feedback metric for both teachers and students on how well the teaching is going than an actual assessment of how well the student is mastering the material or how good they are at academics "in general".  The idea of averaging the farking grades from different courses for every different student and then comparing the final results (which may be the average of completely different course schedules) is, in a word, batshiat.  If you actually go further into academics than undergrad you'll actually find that 100% of every research and graduate program on the planet agrees with me here, the lessons on how irrelevant and meaningless GPA actually is are called "quals".  Unfortunately, as much as I'd like to make this argument, both businesses hiring from academic institutions and most undergraduate programs are run by idiots who know nothing about anything and less about teaching, so... we've sadly lost the overall cultural fight on that one.  Sorry.
