It is only easier in the sense of not having to install or use a password manager, and that the email addresses themselves are not as sensitive as the password. As with everything security related, there is a trade-off. I'm not saying it's more secure, but it can be more convenient in certain circumstances and for certain people. A password-manager is more secure (if the master password is and the manager software is safe). A unique email address + unique password with a password manager even more so. two-factor authentication even more... and so on... It's just a question of options/priorities. This is still a valid option in my opinion which might work well for some people who don't want / can't use a password manager, but can handle a list of random email addresses...
