That is a problem with you not understanding how security works.

> If you really wanted to be secure

There is no such thing as "being really secure". There are threat models, and implementations that defend you against them. Because you can't prevent a bulldozer from destroying your front door does not mean that it is useless to ever lock it.

Even your air-gapped example is wrong, because it means that you have to trust that system (unless you are capable of building a computer from scratch in your garage, which I doubt).

Sending an encrypted over the Signal app is a lot more secure than sending an email over the ProtonMail website, which itself is more secure than sending it in a non-secret Telegram channel. It's a gradient, it can be "more" or "less" secure, it doesn't have to be "all or nothing" as you seem to believe.
