We already know that mathematically your answer is correct, but the fact is that we're saying you shouldn't use probability at all in that instance. Why? Well, because there's nothing to guarantee that you won't end up infinitely choosing to switch to the wrong door.
When you add up the number of options however, that problem dissolves and your probability theory proves to be effective. For instance when there are a million doors to choose from. But not when there are only a few of them.
--- THe problem is still there, but it's much more of a leap to say that you won't get the right answer as the number of doors increases.
What do you mean infinitely choosing the wrong door?
