There are some decentralised solutions for this issue such as Tor. With Tor, every domain generates their own public/private key pair (which represents the domain itself) hence making it impractical for actors to break all of them (in fact, breaking even one of the 128-bit ed25519 keys would be a breakthrough in cryptography). The primary issue with this is that centralised services have a much greater network effect so this cannot be relied upon for everything.
