I think teaching your dog to enjoy the crate and go into it without freaking out is very valuable, even if you don't end up crating your dog at all during the day. You never know if you're going to be in a situation where you need to keep your dog in a crate, and you don't want them panicking because this is something completely new to them.
For example, I live in an area where a hurricane evacuation could happen any time between the months of June through end of October. If I ever needed to evacuate up North and stay in a motel, or with a friend, there is a good chance my dog will need to be able to stay in a crate. Especially in a motel! And this has happened before. In 2005, right after Hurricane Katrina, Houstonians were very on edge about Hurricanes after seeing what happened to New Orleans. So we had Hurricane Rita coming our way, and everybody evacuated (and gridlocked all the freeways). My family went to Dallas and stayed with family. We brought both our dogs, and they had to be crated sometimes because there were other dogs and if we left, we weren't comfortable leaving them roaming an unfamiliar house.
So I think having a crate on hand, and teaching your dog to like the crate, is very important in case of emergencies.
