AFAIK, This isn't entirely accurate. If you wanted to throw a dagger after your first attack, you would have to sheath your rapier as a free action and draw a dagger as a free action, or drop your rapier and draw a dagger as a free action, then throw. If you choose not to drop or stow away your rapier, you must use your other hand to throw the dagger. If you use your other hand at the same time you use your primary hand, you are now attacking with two weapons, and you suffer the penalties appropriate for doing so.
Sheathing is an MEA, actually.
Past that, I disagree with you. You are not getting the benefit (that is to say, an extra attack), therefore, you do not take the penalty.
Here's the quote from the SRD:
If a normal character (i.e. a character without the multiattack and/or multidexterity feats) wields a second weapon (fights two handed), that character
can get one extra attack per round with that weapon. Fighting in this way is very hard, however, and the character suffers a -6 penalty for regular attacks with the first hand and a -10 penalty to the attack with a other hand.
So...you
can take an extra attack, but you do not have to. The rest of it hinges on how you interpret "fighting in this way" - I believe it is meant to mean "fighting in such a way that you get an extra attack with your second weapon".
Further evidence:
Character has three attacks and Ambidexterity. He has a longsword in his right hand, and nothing in his left. He attacks with the longsword once. Then, he uses a free action to switch hands. He attacks with the longsword in his left hand, uses a free action to switch it back, and attacks with the right hand. Does he take the two-weapon fighting penalty? Of course not. He's only using one weapon.
What about Mr. Quick-Draw? He attacks once, drops his weapon, draw another, and attacks again. Does
he take the two-weapon fighting penalty? Of course not. He's fighting with two weapons, but he's only using one weapon at a time.
So, when you think about it, is the dagger throwing rapier wielder. He's just changing which single weapon he's using during the round - the same as someone who is swapping hands or using quickdraw.
If you don't allow this, then you run into the ridiculous situation where someone (with quickdraw) could attack with a rapier, drop it, draw a dagger, throw it, then draw a second rapier...and do it all with no penalty...while the guy with a rapier in one hand and a dagger in the other couldn't do the same.
