Well, it's not because Apple doesn't give access to parts, otherwise it would be.

Not sure how use of hot air station suddenly makes it something that a user can't do?

You can buy a hot air station for less than $100 and it will do the job. Only caveat is that the replacement part needs to be new (so it has pre-applied solder balls) - otherwise you'd need to reball which a bit more difficult, but not something that can't be done at home.

A bit like saying your car's engine is user replaceable. It is but it's wildly out of the skill set of most users.
