I appreciate that answer, it makes sense that it is based on the country. What I'm hoping to avoid is having to give my actual identity to all services on the internet. It will just allow terrible monitoring and oversight that isn't helpful for democracy. I don't trust the current us administration to know everything I say, everything I do, I don't really trust any government to have that power (and I want to stop crime and abuse..). I like some privacy. We are heading to that already with the Texas and Florida age requirements on the internet today.
This matrix discussion here is missing the point - many people don't want ubiquitous tracking of everything we do on the internet. You and matrix are seemingly not honestly addressing that point, because matrix doesn't seem different discord (in the requirements).
We're taking it for granted that people do not want to be tracked on the internet, and certainly don't want everyone to have to verify themselves on every site they use. I personally spent ages of time campaigning against the legislation (and lost) - e.g. https://matrix.org/blog/2021/05/19/how-the-uk-s-online-safet... and https://element.io/blog/the-online-safety-bill-an-attack-on-... etc.
The difference with Discord is that Matrix is a protocol, not a service. It's made up of thousands of servers run by different people in different countries. Public instances may choose to verify users in affected countries to abide by the law; others may choose to run a private instance instead.
