@lemonflavoured I can't say I've always wondered, but that is an interesting question! https://constitutioncenter.org/the-constitution/articles/article-iv/clauses/42
"In cases such as Pacific States Telephone & Telegraph Co. v. Oregon (1912), the Supreme Court has refused to invalidate various forms of direct democracy permitted by state law, such as popular initiative and referendum, on the ground that they violate the Guarantee Clause"
SECTION. 1. Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof.
@BenAveling @Gargron But yes, perhaps even in the absence of federal govt, you simply have to adhere to the other server's rules when interacting with people on that server... gets tricky for when you're just posting out into the void. Seems unfair for the rules of every single one of your followers' servers to apply to all of your posts.
I don't have answers- I just think this is the correct framing and right way to approach these issues.
@Varpie @BenAveling @Gargron Perhaps. I agree- there would be servers that do not accept the constitution. There could be servers that accept a different set of rules that is unpalatable to the majority of instances which adopt the constitution and therefore they defederate from those instances.
I guess the question is: could some centralization actually be good? (A conference; a virtual conference; a meet up for admins; a global support team that helps admins fight fires).
