Pragmatically, we all want the MMU to work and for pointers to address the correct logical address. No one is keeping anything valuable from you by preventing this. It's not like a DRM scheme.

As I understand it, this can be used to access secrets of various secure enclaves on affected systems (potentially TPM in firmware, SGX, ARM Trustzone etc, depending on what the platform in question has). In which case it absolutely is used for DRM on some devices.
And as I pointed out in the comment you are responding to, there are plenty of other reasons to want complete control of my computers. Härd realtime behaviour is especially important to me, as is the principle of FOSS.
