IP addresses are just a different type of name, and also assigned by hierarchical entities. NAT isn't the issue, rather it's the incumbent power structures gradually tightening the identity/control screws. If you have a public IP on your physical connection and use that for banned publishing, they go after the account holder listed for the physical connection, which eventually gets back to you - the same as if you obtain that public IP from Digital Ocean or a tunnel broker.
The only way around that is using naming systems that don't rely on centralized authorities, or at least can't be coerced by governments.
