Okay, now try to.

You need an existing account, which you can't get if you:

- disable javascript

- don't verify with a phone number

- get stuck in captcha hell

verify with a phone number is notorious for blocking google voice number blocks and detecting devices that aren't pinging cell towers

If I was that concerned, I'd get a burner phone with a prepaid SIM card and create my account from a public computer while covering my face.

Plus, as somebody else already said: having JS enabled seems pretty much mandatory if you want to be able to decrypt your emails client-side.

In the EU countries, it has (by law) become very hard to obtain an anonymous prepaid SIM card.

In _some_ EU countries. That's not true for them all.

> disable javascript

How do you want to decrypt your data client-side without running a software to do just that?
