People don't type addresses, they open google, type "facebook" there and click the first link. Phishing often relies on similarity between different domain names. Switching to tor domains will remove assumption of reliability of domain name reading.

It will be harder to verify whether an address is real or fake. You would have to trust the search engines. Offloading the responsibility to google basically makes google the DNS provider

Phishing wouldn't work if addresses were easy to verify. And safe browsing services wouldn't be needed either.

And replaces it with what exactly? A trusted source of truth? Meaning Google? Haha.

There is approximately zero overlap between the userbase of Tor and the group of people who get to Facebook by Googling "facebook".

Userbase of tor has no problem with onion domains.

I do :)

I don't know how you got here today but I:

    1. Opened a new tab.
    2. Pressed the n key.
    3. Pressed enter.

Where does it matter if it's readable if I have bookmarks?

Readable addresses means you can go to some site for the first time and be sure it's the address you wanted. It's not a SHA256 checksum, but it's human-doable in some seconds.
