It is indeed a great skill, but time is limited and it feels so incredibly futile to spend 30 minutes preparing nice food for the millionth time, when in 10 minutes it will only be a memory in my stomach.
(edit: removed a superfluous link, so instead I'll just be anecdotal. Cooking and eating are great social activities when done right. In my mind it's incredibly relaxing to cut vegetables and manage a meal. Conversations can spring into new inspiration or just better bonding with friends. I understand that not all meals can put striving for that kind of bliss as a major goal, but I'm not trying to defend all meals.)
