nostr:npub1u27r9h3j9pvrplaffsmpn698e8xhmuqhdgcxldv67ammql9pumnqha3qfq you can just start a California coop. Non-residents can be members.
For #CoSocialCa we restrict membership to Canadian residents because most privacy, copyright, consumer protection etc. laws apply nationally. It's hard enough to run a good service domestically without having to deal with remote members.
But different coops have different needs.
