You are correct about freedom but incorrect about access. Relays are considered as websites & they do provide a service which is a social network. Not everyone may be owned by a corporation but running a social network is a business & there are laws for internet & businesses. You cannot just discriminate & remove people for no reason just because you don't like them. This is why the BBB & FTC exists to ensure fair practice.
Just like how you can take it to court for any mainstream platform like facebook, x, or reddit nostr is no different. You just have a harder time finding out who to prosecute unless you know how to identify relay providers. Just because you can go to another site like how instead of x you can go to mastodon or like reddit you can go to lemmy instead does not mean they are above the law because alternatives are available.
If that were the case then you wouldn't even be able to hold video game companies liable for unethical bans.
