Authenticate where? How does the authentication prove that the intended recipient is the one who has clicked on the link and should be able to view? What happens if the email is forwarded with the link? What should one do to forward the email to someone without this encryption?
Organizations may need ways to store, archive and manage received email content from others.
I don’t understand what problem this solves for organizations and how.
Microsoft Outlook 365 has a somewhat similar feature where the email is just a link to hosted content on its servers (this kind of functionality isn’t new or recent on other platforms). It doesn’t require any authentication by the recipient. IIRC, the sender can also decide on the expiry of the content.

You log in with a Google account associated with the recipient address. You prove you control the email by putting in a code Google sends you.
> What happens if the email is forwarded with the link?
They can't open it because they don't have access to the Google account associated with your email address.
> What should one do to forward the email to someone without this encryption?
Obviously, encrypted emails are not meant to be forwarded. Nothing prevents you from taking a photo though. Maybe copy and paste will work.

Organizations can't control how they receive information. It doesn't matter what they want in this regard. If a judge orders them to do something about it, that's for the judge to figure out.

It keeps messages private. You don't see why organizations in e.g. health care, law, or the military want increased privacy of messages in a way that is super easy to use? And where recipients can't accidentally forward sensitive messages? A lot of this is determined by compliance requirements too.
I have used a similar service. Anytime you want to access the link, you must enter a code sent to your email. So if you forward the link, and the person to whom you forward it click the link, they need you to also forward the code to them.
