So the recommendation here is just to use Chat clients to communicate and forget about Email? Well that is hardly a good solution.

Yes. Email is designed to be stored forever, and all attempts to do otherwise fail due to the design of email clients. Chat is possible to designed to self-destruct. Anyone can screenshot either, so there’s no use worrying about that.
Yes! E-mail is fundamentally terribly positioned to do secure messaging. You can use e-mail, or you can have cryptography that works and have people use it, but you can't do both.

E-mail is fundamentally a way to send a sequence of bytes somewhere (untrusted) so they can be picked up later by someone (trusted).
That’s also literally what Signal is built on so I think you’re overstating the difference.
Secure messaging is much more complex, but here’s a simple example of how that’s not true: TCP is bidirectional and email is one message, fire and forget. That immediately affects your ability to have forward and backward secrecy.
