I'm not saying they were designed to _prevent_ access. They just weren't chosen with a priority on home users being able to open them, because Apple doesn't expect home users to open their devices. And that's true for like 95% of users.

By comparison, if Ikea sold you a desk and used torx screws (and didn't provide a driver) that would be pretty obnoxious, so they're either going to use standard heads or provide a driver.
