Just my opinion, but I feel Kensington locks have little value.

Sure, maybe it will deface the stolen item when it gets ripped off, but for a thief, the device is still usable, and it can be sold for parts or at a discount. We are talking about the sorts of people that steal bicycle wheels and seats.

Their utility is in keeping honest people honest. For example, keeping office workers or customers from just walking off with or moving assets.

Here we're literally talking about protecting the device while the user is actively using it! Just preventing someone from grabbing it by hand for 5 seconds is a huge win.
