Because, we care about optimizing our day, we are ride centric, and its important for us to not only get the attractions we want, but also at the times we want.
The closer we get to the 30 and day before the less chance there is in doing exactly that.
With the addition of FP+ to new attractions and the increased capacity devoted to FP+ there is an increased downside risk to not using FP and that risk escalates every day you wait to book your FPs.
This doesn't mean that its not possible the night before, the day of even, you could book what you wanted when you wanted, but the likely hood goes down by the day, by the hour even.
Book asap, you are paying thousands of dollars for this vacation, you should get to most out of your money.
