I generally couldn't give a fuck about what's playing on the radio. My privacy, as and when I choose it to be my privacy, is a tad more important than some hit parade melody. Regardless of context.

That's just nonsense. What is implied here is that there are several layers of magnetism to each physical bit on a platter. Of course we know this is not possible. Each bit, like any magnet in the known universe has just a north and a south pole. If the state of that bit and all other bits that relate to it are changed then it's simply impossible to to know what state or states it has ever been in.
It's not mystical 'layers' that are exploited but the physical (as opposed to logical) storage characteristics with their error detection and correction technologies (amongst other aspects). Decent erasure software is of course aware of these methods and also exploits them in such a way that there will be no going back.
Applying a proper erasure method to the contents of a hard disk is just as effective as physical destruction but of course retains the functionality of the hard disk. This is what should be encouraged and it would be a fine thing indeed to find such functionality built into operating systems, or maybe even the hard disks themselves, right from the start.
