But the problem with your argument is you are assuming they did nothing to protect their privacy. They specifically addressed the email to someone. Or had it specifically addressed to them.
As the other poster said, consider the urinal. Whether intended or not, there are about to be a lot of images of people at the urinal taken by a capture device. Should men just get used to this idea and expect these pictures online?
I roughly get and agree with what you are saying. But, consider, it is trivial to build a microphone that can pick up every word you said within your house. Do you feel that police should be able to use such a device from a van outside without a warrant? Hell, it is trivial to build a camera that can see through most clothes nowdays.
That is, the laws are there precisely to cover things which may be easy otherwise. Hell, it is trivial not to pay your taxes. Illegal. It is trivial not to honor a contract. Illegal. We don't make laws against jumping to the moon. Because... not exactly relevant from a legal perspective.

Yes, or else just walk to the stall and pee in the toilet. I see guys doing that all the time where I work -- some men want to be private about it, and urinals are not and have never been private.

I did say that closing your door should give you a reasonable expectation of privacy. I also said that things that are easy and popular should not be made illegal. If everyone walked around with a parabolic microphone or a millimeter wave scanner, we would have to adjust our laws, habits, and notions of what counts as a reasonable expectation of privacy accordingly. It is currently reasonable to expect that wearing clothes protects you from having your naked body photographed; that would have to change if it were common for people to carry cameras that could see through cotton.
You missed the point of my last question. Right now. Today. You have an expectation of privacy in your own home. For anyone that understands how surveillance works, you would know that closing your door is pointless as far as keeping the sound in. By your logic, this is not appropriate. Because, "hey, you should know that it is easy to hear inside your home."
However, if police wish to violate this, using relatively common and accessible tools, they have to have a warrant. Consider the phone calls you place. These are just as exposed to third parties as any email you send. Yet to intercept them police need a warrant. For others to do so is illegal.
Note, the deciding point here is not that it is hard or easy to intercept your communications. Or sit outside with a microphone. The point is that those activities require a warrant. Because they are illegal otherwise.
