"programmers naturally expect a function to return at the very end"

I disagree. I expect a function to return at the moment the final result is known. The decisions and logic are over. I shouldn't have to glaze over even a single extra line of code, because the work has already been done.

That's a fair point. I guess the main argument in favor of single return statements in modern programming languages is ease of debugging and logging. Like most things in programming, you have to consider the trade-offs. A few return statements isn't the end of the world, but after too many you might just want to make some more functions.
