Centralized CAs were and are a mistake. HTTPs should work more like ssh-keys where the first time you connect to a website it's untrusted, but once you have validated it the website you want, it never bothers you again unless the private key changes. Private key rotations can be posted on public forums, or emailed, or any number of other ways and users that don't care can ignore the warnings like they do anyway, while users who DO care, can perform their own validation through other channels.
The most important aspect is that there is no "authority" that can be corrupted, except for the service you are connecting to.
