Flaw: if you are to remember the day, it does have an effect. So what you would do is request the designs for technology that would give you anything you want, remember those plans, and rebuild.

It's really a hypothetical question. The situation I described doesn't have to be logical. Just assume it's true for the sake of answering the question. The dilemma is deciding whether to continue the day, not trying to find loopholes or logic flaws.

The existence of loopholes is essential to the answer I would give. It's not interesting at all to just say one's instant reaction and leave the thread.
