My solution for your concerns is twofold:

1. Use a password-based encryption method (not tied to hardware identity) if you prioritize moving the disk around. Then it is just as readable in a spare machine.

2. Use an easy to remember password/passphrase and write it down somewhere you keep paper documents, if you prioritize recovery.

This still provides meaningful protection when you need to discard the drive. The random downstream recipient of the hardware will not know your password, even if you skip the step where you "crypto-shred" the drive by setting a new random password.
