They can't fire you if you've already quit.

The two week period is for your teammates' benefit. Not your company or the project. Any manager that knows they're losing someone is going to much rather spend money on hiring and ramping up a replacement than continuing to employ the person who's leaving. She won't care what you do.

But it is just one paycheck out of 24 per year that will now be returned to the budget. Shutting the door on an employee who's trying to be professional and give 2 weeks notice makes a manager look petty and sends the message that the project is in maximum cost cutting mode - that gaining a single paycheck for one person is worth depriving the other employees of any chance of getting needed knowledge or context from the person who resigned. To me that's a sure sign that layoffs are coming.
