Lemmy can work without user accounts made directly on the server. I’m posting from a completely different instance using completely different software (mbin), and I can see both .ml and .world and interact with them both just fine despite their defederation from each other.
It’s kind of more like a random street gathering instead of an exclusive club.

Or like the golden age of instant messengers, where you had multiple choices of multi-client apps like Trillian.
You still had individual accounts for each IM platform, but a single app to chat on any platform.
