But, houses have locks on the doors. The whole point of the house is to be a safe for people. Security is all about the threat model, your risk assessment should inform the security measures that make sense in the security/convenience continuum. Not everyone will be equally well served by the exact same risk mitigation methods.

The point of whole disk encryption is to delay or nullify physical device control. If your disk is not encrypted, but you have a single encrypted file a bad actor wants to access. If they get physical control, then it is game over. They have all the time and power in the world to crack down that one file. Now, most people don't have any one file(s) like that, but instead are worried about their private life in general. Without encryption, physical access to the device means total access to their entire life, the house had no locks and the thieves just waltzed in and took everything of value. Whole disk encryption is opting for a sturdier door, with better locks. Physical control is still bad, but access is orders of magnitude harder. Sure, if you lose the only key to your house, you better be prepared to break windows or walls to get in, but that is a user responsibility.
