that's the idea behind SecureBoot and the TPM chip is to provide the GDID based on hardware fingerprint. Some games already do this as "anti-cheat" measurements (tracking you) and Microsoft has been doing it since Windows 7 days. It's just that the TPM now gives you that hardware authority.

replyhard drive and motherboard serials have been around far longer than TPMs. Not to mention TPMs are far cheaper to replace than hard drives.
Poster might mean that the TPM gives you some degree of non-repudiation since the TPM can cryptographically sign stuff.
