Because it's not meant for you to skip all the races. It's meant to be a deterrant. Similar to why it's more expensive to use the "Buy It Now" option for a vehicle rather than waiting for it to unlock. If you really want to do it, you can, but you will pay a penalty for that.

To answer your 2nd question, yes you will be able to buy any cars you did not win after the event has ended (March 4th).
