The reasoning behind why the Laws are why they are is very complex and comes from much arguing. You see the position of not noticing partner has put the wrong card out as similar to a call out of turn - I don't, and judging by what the law-makers have done, nor do they.
As to the suitability of this forum for this type of post I do not mind it, but please put posts about what the Laws should be in a separate thread [which is why I have split your post off]. Most people come to this forum to find out what the Laws are, not what they should be.
In fact, while we shall not stop anyone starting such a thread, it probably is not the best place for it. I would advise that if you want to discuss why the Laws are as they are you should pick a newsgroup, typically rec.games.bridge, or the bridge-laws mailing list. Details of how to find these and other newsgroups are at Bridge newsgroups and mailing lists
