TPM based disk encryption is mostly useful as theft protection, so that companies, education facilities or government agencies can provision 100,000 devices without having to match smartcards/fobs/disk passwords to devices and users. (Which often leads to terrible security practices, like backup passwords shared between devices etc.) So cracking it in 3 hours by amateurs is pretty bad, because now even not too sophisticated thieves can start looking for crypto wallets or sensitive data to ransom.
