True, there are arguments but i would say they're pretty weak.
Though emails are stored by third parties, those parties state that they won't read your email. That makes it reasonable to assume that they won't read your information and further reasonable that your communication will remain private due to those statements.
Yes email travels unencrypted through mail servers but it's not a requirement that someone read the message to pass it though the server. Someone has to overtly snoop on the message to break the users privacy. Much like a phone call passes through telco offices and someone can snoop on a call by taping two copper wires.
Contrast that with sending a telegram to someone over the phone. In order for the message to go out you have to tell the 3rd party what it says so they can type it for you.
A letter that's sealed can still be read fairly easily. If not by breaking the seal with steam then simply by someone holding it up to a light. The seal is a very weak protection mechanism.

Edit: flow of statements.
