It takes more than 30 seconds just to take the ingredients for a pie crust out of the cupboard so your time estimate is a bit off. Not to mention the extra time to do the dishes. The time it takes for a pie crust to defrost is time that doesn't involve you because you're probably not there watching it defrost but doing something else (playing with your kids, helping them with homework, paying bills -yuck!).
Look, I'm a fiend about making things from scratch. I don't like to take shortcuts because I enjoy cooking immensely and being a single person with no kids allows me time to do it. But I don't look down on people who need to take shortcuts (for whatever reason) or the TV cooks who help people (sometimes people who have no idea how to cook and would be bringing home a bucket of KFC otherwise) by giving easy recipes that can involve things such as pre-made pie crusts.
