CAs are CAs because they established themself. Personally I don't trust them because they are susceptible to MitM attacks & government intervention attacks.

Some Mesh Networks & protocols like the Tor Browser use an IP derived from a public key.. so you're absolutely sure that who you're talking to is who they say they are.

Why can't we have our cake (long distance electronic communications) and eat it too? (encryption & assuredness of identity)

Celebrating "trustedness" of LetsEncrypt only perpetuates the belief that CA is working fine.
