It's definitely a hard problem. I definitely don't agree that companies need to host speech. Freedom of speech also means freedom from compelled speech. I think a good boundary is to define whether an entity is actually hosting speed or providing general communications services. Platforms like facebook are the latter. Comments and photos exist on their servers, and they have a right not to host speech they don't want. But things like DNS providers are more akin to paper produces in your analogy. And things like banking services are a whole different story. I see no reason why they shouldn't be regarded as utilities like telecoms, mail carriers, etc. I think banks have to honor checks. Maybe there's a startup idea in letting people send paper checks through the mail via an app?
