Generally commercial drive encryption solutions, like Bitlocker, usually has a backup recovery key that can be used to access the encryption key if your TPM is reset, or if your device dies.

So I guess the short answer is most of these solutions don't fully protect it from being moved to another device, they just add another layer of security and hassle that makes it harder to do. And without the TPM as part of these solutions, you would be entering a 48-character passphrase every time you boot your device, which has several security flaws of its own.
